     * @cfg {Object} config
     *
     * List of configuration options with their default values.
     *
     * __Note:__ You need to make sure {@link Ext.Base#initConfig} is called from your constructor if you are defining
     * your own class or singleton, unless you are extending a Component. Otherwise the generated getter and setter
     * methods will not be initialized.
     *
     * Each config item will have its own setter and getter method automatically generated inside the class prototype
     * during class creation time, if the class does not have those methods explicitly defined.
     *
     * As an example, let's convert the name property of a Person class to be a config item, then add extra age and
     * gender items.
     *
     *     Ext.define('My.sample.Person', {
     *         config: {
     *             name: 'Mr. Unknown',
     *             age: 0,
     *             gender: 'Male'
     *         },
     *
     *         constructor: function(config) {
     *             this.initConfig(config);
     *
     *             return this;
     *         }
     *
     *         // ...
     *     });
     *
     * Within the class, this.name still has the default value of "Mr. Unknown". However, it's now publicly accessible
     * without sacrificing encapsulation, via setter and getter methods.
     *
     *     var jacky = new Person({
     *         name: "Jacky",
     *         age: 35
     *     });
     *
     *     alert(jacky.getAge());      // alerts 35
     *     alert(jacky.getGender());   // alerts "Male"
     *
     *     jacky.walk(10);             // alerts "Jacky is walking 10 steps"
     *
     *     jacky.setName("Mr. Nguyen");
     *     alert(jacky.getName());     // alerts "Mr. Nguyen"
     *
     *     jacky.walk(10);             // alerts "Mr. Nguyen is walking 10 steps"
     *
     * Notice that we changed the class constructor to invoke this.initConfig() and pass in the provided config object.
     * Two key things happened:
     *
     *  - The provided config object when the class is instantiated is recursively merged with the default config object.
     *  - All corresponding setter methods are called with the merged values.
     *
     * Beside storing the given values, throughout the frameworks, setters generally have two key responsibilities:
     *
     *  - Filtering / validation / transformation of the given value before it's actually stored within the instance.
     *  - Notification (such as firing events) / post-processing after the value has been set, or changed from a
     *    previous value.
     *
     * By standardize this common pattern, the default generated setters provide two extra template methods that you
     * can put your own custom logics into, i.e: an "applyFoo" and "updateFoo" method for a "foo" config item, which are
     * executed before and after the value is actually set, respectively. Back to the example class, let's validate that
     * age must be a valid positive number, and fire an 'agechange' if the value is modified.
     *
     *     Ext.define('My.sample.Person', {
     *         config: {
     *             // ...
     *         },
     *
     *         constructor: {
     *             // ...
     *         },
     *
     *         applyAge: function(age) {
     *             if (typeof age !== 'number' || age < 0) {
     *                 console.warn("Invalid age, must be a positive number");
     *                 return;
     *             }
     *
     *             return age;
     *         },
     *
     *         updateAge: function(newAge, oldAge) {
     *             // age has changed from "oldAge" to "newAge"
     *             this.fireEvent('agechange', this, newAge, oldAge);
     *         }
     *
     *         // ...
     *     });
     *
     *     var jacky = new Person({
     *         name: "Jacky",
     *         age: 'invalid'
     *     });
     *
     *     alert(jacky.getAge());      // alerts 0
     *
     *     alert(jacky.setAge(-100));  // alerts 0
     *     alert(jacky.getAge());      // alerts 0
     *
     *     alert(jacky.setAge(35));    // alerts 0
     *     alert(jacky.getAge());      // alerts 35
     *
     * In other words, when leveraging the config feature, you mostly never need to define setter and getter methods
     * explicitly. Instead, "apply*" and "update*" methods should be implemented where necessary. Your code will be
     * consistent throughout and only contain the minimal logic that you actually care about.
     *
     * When it comes to inheritance, the default config of the parent class is automatically, recursively merged with
     * the child's default config. The same applies for mixins.

/**
 * @class  Ext.ClassManager
 *

 *
 * Ext.ClassManager manages all classes and handles mapping from string class name to
 * actual class objects throughout the whole framework. It is not generally accessed directly, rather through
 * these convenient shorthands:
 *
 * - {@link Ext#define Ext.define}
 * - {@link Ext.ClassManager#create Ext.create}
 * - {@link Ext#widget Ext.widget}
 * - {@link Ext#getClass Ext.getClass}
 * - {@link Ext#getClassName Ext.getClassName}
 *
 * ## Basic syntax:
 *
 *     Ext.define(className, properties);
 *
 * in which `properties` is an object represent a collection of properties that apply to the class. See
 * {@link Ext.ClassManager#create} for more detailed instructions.
 *
 *     @example
 *     Ext.define('Person', {
 *          name: 'Unknown',
 *
 *          constructor: function(name) {
 *              if (name) {
 *                  this.name = name;
 *              }
 *
 *              return this;
 *          },
 *
 *          eat: function(foodType) {
 *              alert("I'm eating: " + foodType);
 *
 *              return this;
 *          }
 *     });
 *
 *     var aaron = new Person("Aaron");
 *     aaron.eat("Sandwich"); // alert("I'm eating: Sandwich");
 *
 * Ext.Class has a powerful set of extensible {@link Ext.Class#registerPreprocessor pre-processors} which takes care of
 * everything related to class creation, including but not limited to inheritance, mixins, configuration, statics, etc.
 *
 * ## Inheritance:
 *
 *     Ext.define('Developer', {
 *          extend: 'Person',
 *
 *          constructor: function(name, isGeek) {
 *              this.isGeek = isGeek;
 *
 *              // Apply a method from the parent class' prototype
 *              this.callParent([name]);
 *
 *              return this;
 *
 *          },
 *
 *          code: function(language) {
 *              alert("I'm coding in: " + language);
 *
 *              this.eat("Bugs");
 *
 *              return this;
 *          }
 *     });
 *
 *     var jacky = new Developer("Jacky", true);
 *     jacky.code("JavaScript"); // alert("I'm coding in: JavaScript");
 *                               // alert("I'm eating: Bugs");
 *
 * See {@link Ext.Base#callParent} for more details on calling superclass' methods
 *
 * ## Mixins:
 *
 *     Ext.define('CanPlayGuitar', {
 *          playGuitar: function() {
 *             alert("F#...G...D...A");
 *          }
 *     });
 *
 *     Ext.define('CanComposeSongs', {
 *          composeSongs: function() { }
 *     });
 *
 *     Ext.define('CanSing', {
 *          sing: function() {
 *              alert("I'm on the highway to hell...");
 *          }
 *     });
 *
 *     Ext.define('Musician', {
 *          extend: 'Person',
 *
 *          mixins: {
 *              canPlayGuitar: 'CanPlayGuitar',
 *              canComposeSongs: 'CanComposeSongs',
 *              canSing: 'CanSing'
 *          }
 *     });
 *
 *     Ext.define('CoolPerson', {
 *          extend: 'Person',
 *
 *          mixins: {
 *              canPlayGuitar: 'CanPlayGuitar',
 *              canSing: 'CanSing'
 *          },
 *
 *          sing: function() {
 *              alert("Ahem...");
 *
 *              this.mixins.canSing.sing.call(this);
 *
 *              alert("[Playing guitar at the same time...]");
 *
 *              this.playGuitar();
 *          }
 *     });
 *
 *     var me = new CoolPerson("Jacky");
 *
 *     me.sing(); // alert("Ahem...");
 *                // alert("I'm on the highway to hell...");
 *                // alert("[Playing guitar at the same time...]");
 *                // alert("F#...G...D...A");
 *
 * ## Config:
 *
 *     Ext.define('SmartPhone', {
 *          config: {
 *              hasTouchScreen: false,
 *              operatingSystem: 'Other',
 *              price: 500
 *          },
 *
 *          isExpensive: false,
 *
 *          constructor: function(config) {
 *              this.initConfig(config);
 *
 *              return this;
 *          },
 *
 *          applyPrice: function(price) {
 *              this.isExpensive = (price > 500);
 *
 *              return price;
 *          },
 *
 *          applyOperatingSystem: function(operatingSystem) {
 *              if (!(/^(iOS|Android|BlackBerry)$/i).test(operatingSystem)) {
 *                  return 'Other';
 *              }
 *
 *              return operatingSystem;
 *          }
 *     });
 *
 *     var iPhone = new SmartPhone({
 *          hasTouchScreen: true,
 *          operatingSystem: 'iOS'
 *     });
 *
 *     iPhone.getPrice(); // 500;
 *     iPhone.getOperatingSystem(); // 'iOS'
 *     iPhone.getHasTouchScreen(); // true;
 *
 *     iPhone.isExpensive; // false;
 *     iPhone.setPrice(600);
 *     iPhone.getPrice(); // 600
 *     iPhone.isExpensive; // true;
 *
 *     iPhone.setOperatingSystem('AlienOS');
 *     iPhone.getOperatingSystem(); // 'Other'
 *
 * ## Statics:
 *
 *     Ext.define('Computer', {
 *          statics: {
 *              factory: function(brand) {
 *                 // 'this' in static methods refer to the class itself
 *                  return new this(brand);
 *              }
 *          },
 *
 *          constructor: function() { }
 *     });
 *
 *     var dellComputer = Computer.factory('Dell');
 *
 * Also see {@link Ext.Base#statics} and {@link Ext.Base#self} for more details on accessing
 * static properties within class methods

 * @class Ext.Loader

 * @aside guide mvc_dependencies
 *
 * Ext.Loader is the heart of the new dynamic dependency loading capability in Ext JS 4+. It is most commonly used
 * via the {@link Ext#require} shorthand. Ext.Loader supports both asynchronous and synchronous loading
 * approaches, and leverage their advantages for the best development flow.
 * We'll discuss about the pros and cons of each approach.
 *
 * __Note:__ The Loader is only enabled by default in development versions of the library (eg sencha-touch-debug.js). To
 * explicitly enable the loader, use `Ext.Loader.setConfig({ enabled: true });` before the start of your script.
 *
 * ## Asynchronous Loading
 *
 * - Advantages:
 * 	+ Cross-domain
 * 	+ No web server needed: you can run the application via the file system protocol (i.e: `file://path/to/your/index
 *  .html`)
 * 	+ Best possible debugging experience: error messages come with the exact file name and line number
 *
 * - Disadvantages:
 * 	+ Dependencies need to be specified before-hand
 *
 * ### Method 1: Explicitly include what you need: ###
 *
 *     // Syntax
 *     // Ext.require({String/Array} expressions);
 *
 *     // Example: Single alias
 *     Ext.require('widget.window');
 *
 *     // Example: Single class name
 *     Ext.require('Ext.window.Window');
 *
 *     // Example: Multiple aliases / class names mix
 *     Ext.require(['widget.window', 'layout.border', 'Ext.data.Connection']);
 *
 *     // Wildcards
 *     Ext.require(['widget.*', 'layout.*', 'Ext.data.*']);
 *
 * ### Method 2: Explicitly exclude what you don't need: ###
 *
 *     // Syntax: Note that it must be in this chaining format.
 *     // Ext.exclude({String/Array} expressions)
 *     //    .require({String/Array} expressions);
 *
 *     // Include everything except Ext.data.*
 *     Ext.exclude('Ext.data.*').require('*');
 *
 *     // Include all widgets except widget.checkbox*,
 *     // which will match widget.checkbox, widget.checkboxfield, widget.checkboxgroup, etc.
 *     Ext.exclude('widget.checkbox*').require('widget.*');
 *
 * # Synchronous Loading on Demand #
 *
 * - *Advantages:*
 * 	+ There's no need to specify dependencies before-hand, which is always the convenience of including ext-all.js
 *  before
 *
 * - *Disadvantages:*
 * 	+ Not as good debugging experience since file name won't be shown (except in Firebug at the moment)
 * 	+ Must be from the same domain due to XHR restriction
 * 	+ Need a web server, same reason as above
 *
 * There's one simple rule to follow: Instantiate everything with Ext.create instead of the `new` keyword
 *
 *     Ext.create('widget.window', {}); // Instead of new Ext.window.Window({...});
 *
 *     Ext.create('Ext.window.Window', {}); // Same as above, using full class name instead of alias
 *
 *     Ext.widget('window', {}); // Same as above, all you need is the traditional `xtype`
 *
 * Behind the scene, {@link Ext.ClassManager} will automatically check whether the given class name / alias has already
 *  existed on the page. If it's not, Ext.Loader will immediately switch itself to synchronous mode and automatic load the given
 *  class and all its dependencies.
 *
 * # Hybrid Loading - The Best of Both Worlds #
 *
 * It has all the advantages combined from asynchronous and synchronous loading. The development flow is simple:
 *
 * ### Step 1: Start writing your application using synchronous approach. ###
 * Ext.Loader will automatically fetch all dependencies on demand as they're 
 * needed during run-time. For example:
 *
 *     Ext.onReady(function(){
 *         var window = Ext.createWidget('window', {
 *             width: 500,
 *             height: 300,
 *             layout: {
 *                 type: 'border',
 *                 padding: 5
 *             },
 *             title: 'Hello Dialog',
 *             items: [{
 *                 title: 'Navigation',
 *                 collapsible: true,
 *                 region: 'west',
 *                 width: 200,
 *                 html: 'Hello',
 *                 split: true
 *             }, {
 *                 title: 'TabPanel',
 *                 region: 'center'
 *             }]
 *         });
 *
 *         window.show();
 *     });
 *
 * ### Step 2: Along the way, when you need better debugging ability, watch the console for warnings like these: ###
 *
 *     [Ext.Loader] Synchronously loading 'Ext.window.Window'; consider adding Ext.require('Ext.window.Window') before your application's code
 *     ClassManager.js:432
 *     [Ext.Loader] Synchronously loading 'Ext.layout.container.Border'; consider adding Ext.require('Ext.layout.container.Border') before your application's code
 *
 * Simply copy and paste the suggested code above `Ext.onReady`, i.e:
 *
 *     Ext.require('Ext.window.Window');
 *     Ext.require('Ext.layout.container.Border');
 *
 *     Ext.onReady(function () {
 *         // ...
 *     });
 *
 * Everything should now load via asynchronous mode.
 *
 * # Deployment #
 *
 * It's important to note that dynamic loading should only be used during development on your local machines.
 * During production, all dependencies should be combined into one single JavaScript file. Ext.Loader makes
 * the whole process of transitioning from / to between development / maintenance and production as easy as
 * possible. Internally {@link Ext.Loader#history Ext.Loader.history} maintains the list of all dependencies your application
 * needs in the exact loading sequence. It's as simple as concatenating all files in this array into one,
 * then include it on top of your application.
 *
 * This process will be automated with Sencha Command, to be released and documented towards Ext JS 4 Final.

 *
 * Ext is the global namespace for the whole Sencha Touch framework. Every class, function and configuration for the
 * whole framework exists under this single global variable. The Ext singleton itself contains a set of useful helper
 * functions (like {@link #apply}, {@link #min} and others), but most of the framework that you use day to day exists
 * in specialized classes (for example {@link Ext.Panel}, {@link Ext.Carousel} and others).
 *
 * If you are new to Sencha Touch we recommend starting with the [Getting Started Guide][getting_started] to
 * get a feel for how the framework operates. After that, use the more focused guides on subjects like panels, forms and data
 * to broaden your understanding. The MVC guides take you through the process of building full applications using the
 * framework, and detail how to deploy them to production.
 *
 * The functions listed below are mostly utility functions used internally by many of the classes shipped in the
 * framework, but also often useful in your own apps.
 *
 * A method that is crucial to beginning your application is {@link #setup Ext.setup}. Please refer to it's documentation, or the
 * [Getting Started Guide][getting_started] as a reference on beginning your application.

     * Ext.setup() is the entry-point to initialize a Sencha Touch application. Note that if your application makes
     * use of MVC architecture, use {@link Ext#application} instead.
     *
     * This method accepts one single argument in object format. The most basic use of Ext.setup() is as follows:
     *
     *     Ext.setup({
     *         onReady: function() {
     *             // ...
     *         }
     *     });
     *
     * This sets up the viewport, initializes the event system, instantiates a default animation runner, and a default
     * logger (during development). When all of that is ready, it invokes the callback function given to the `onReady` key.
     *
     * The default scope (`this`) of `onReady` is the main viewport. By default the viewport instance is stored in
     * {@link Ext.Viewport}. For example, this snippet adds a 'Hello World' button that is centered on the screen:
     *
     *     Ext.setup({
     *         onReady: function() {
     *             this.add({
     *                 xtype: 'button',
     *                 centered: true,
     *                 text: 'Hello world!'
     *             }); // Equivalent to Ext.Viewport.add(...)
     *         }
     *     });
     *
     * @param {Object} config An object with the following config options:
     *
     * @param {Function} config.onReady
     * A function to be called when the application is ready. Your application logic should be here.
     *
     * @param {Object} config.viewport
     * A custom config object to be used when creating the global {@link Ext.Viewport} instance. Please refer to the
     * {@link Ext.Viewport} documentation for more information.
     *
     *     Ext.setup({
     *         viewport: {
     *             width: 500,
     *             height: 500
     *         },
     *         onReady: function() {
     *             // ...
     *         }
     *     });
     *
     * @param {String/Object} config.icon
     * Specifies a set of URLs to the application icon for different device form factors. This icon is displayed
     * when the application is added to the device's Home Screen.
     *
     *     Ext.setup({
     *         icon: {
     *             57: 'resources/icons/Icon.png',
     *             72: 'resources/icons/Icon~ipad.png',
     *             114: 'resources/icons/Icon@2x.png',
     *             144: 'resources/icons/Icon~ipad@2x.png'
     *         },
     *         onReady: function() {
     *             // ...
     *         }
     *     });
     *
     * Each key represents the dimension of the icon as a square shape. For example: '57' is the key for a 57 x 57
     * icon image. Here is the breakdown of each dimension and its device target:
     *
     * - 57: Non-retina iPhone, iPod touch, and all Android devices
     * - 72: Retina iPhone and iPod touch
     * - 114: Non-retina iPad (first and second generation)
     * - 144: Retina iPad (third generation)
     *
     * Note that the dimensions of the icon images must be exactly 57x57, 72x72, 114x114 and 144x144 respectively.
     *
     * It is highly recommended that you provide all these different sizes to accommodate a full range of
     * devices currently available. However if you only have one icon in one size, make it 57x57 in size and
     * specify it as a string value. This same icon will be used on all supported devices.
     *
     *     Ext.setup({
     *         icon: 'resources/icons/Icon.png',
     *         onReady: function() {
     *             // ...
     *         }
     *     });
     *
     * @param {Object} config.startupImage
     * Specifies a set of URLs to the application startup images for different device form factors. This image is
     * displayed when the application is being launched from the Home Screen icon. Note that this currently only applies
     * to iOS devices.
     *
     *     Ext.setup({

     * Please note that there's no automatic fallback mechanism for the startup images. In other words, if you don't specify
     * a valid image for a certain device, nothing will be displayed while the application is being launched on that device.
     *
     * @param {Boolean} isIconPrecomposed
     * True to not having a glossy effect added to the icon by the OS, which will preserve its exact look. This currently
     * only applies to iOS devices.
     *
     * @param {String} statusBarStyle
     * The style of status bar to be shown on applications added to the iOS home screen. Valid options are:
     *
     * * `default`
     * * `black`
     * * `black-translucent`
     *
     * @param {String[]} config.requires
     * An array of required classes for your application which will be automatically loaded before `onReady` is invoked.
     * Please refer to {@link Ext.Loader} and {@link Ext.Loader#require} for more information.

     *
     * @param {Object} config.eventPublishers
     * Sencha Touch, by default, includes various {@link Ext.event.recognizer.Recognizer} subclasses to recognize events fired
     * in your application. The list of default recognizers can be found in the documentation for
     * {@link Ext.event.recognizer.Recognizer}.
     *
     * To change the default recognizers, you can use the following syntax:
     *
     *     Ext.setup({
     *         eventPublishers: {
     *             touchGesture: {

     *                     swipe: {
     *                         // this will include both vertical and horizontal swipe recognizers
     *                         xclass: 'Ext.event.recognizer.Swipe'
     *                     }
     *                 }
     *             }

     *
     * You can also disable recognizers using this syntax:
     *
     *     Ext.setup({
     *         eventPublishers: {
     *             touchGesture: {

     * in your application. The list of default recognizers can be found in the documentation for {@link Ext.event.recognizer.Recognizer}.
     *
     * To change the default recognizers, you can use the following syntax:
     *
     *     Ext.application({
     *         eventPublishers: {
     *             touchGesture: {
     *                 recognizers: {
     *                     swipe: {
     *                         // this will include both vertical and horizontal swipe recognizers
     *                         xclass: 'Ext.event.recognizer.Swipe'
     *                     }
     *                 }
     *             }

     *             // ...
     *         }
     *     });
     *
     * You can also disable recognizers using this syntax:
     *
     *     Ext.application({
     *         eventPublishers: {
     *             touchGesture: {

/**
 * @class Ext.DomQuery
 * @alternateClassName Ext.dom.Query
 *
 * Provides functionality to select elements on the page based on a CSS selector. Delegates to
 * document.querySelectorAll. More information can be found at
 * [http://www.w3.org/TR/css3-selectors/](http://www.w3.org/TR/css3-selectors/)
 *
 * All selectors, attribute filters and pseudos below can be combined infinitely in any order. For example
 * `div.foo:nth-child(odd)[@foo=bar].bar:first` would be a perfectly valid selector.
 *
 * ## Element Selectors:
 *
 * * \* any element
 * * E an element with the tag E
 * * E F All descendant elements of E that have the tag F
 * * E > F or E/F all direct children elements of E that have the tag F
 * * E + F all elements with the tag F that are immediately preceded by an element with the tag E
 * * E ~ F all elements with the tag F that are preceded by a sibling element with the tag E
 *
 * ## Attribute Selectors:
 *
 * The use of @ and quotes are optional. For example, div[@foo='bar'] is also a valid attribute selector.
 *
 * * E[foo] has an attribute "foo"
 * * E[foo=bar] has an attribute "foo" that equals "bar"
 * * E[foo^=bar] has an attribute "foo" that starts with "bar"
 * * E[foo$=bar] has an attribute "foo" that ends with "bar"
 * * E[foo*=bar] has an attribute "foo" that contains the substring "bar"
 * * E[foo%=2] has an attribute "foo" that is evenly divisible by 2
 * * E[foo!=bar] has an attribute "foo" that does not equal "bar"
 *
 * ## Pseudo Classes:
 *
 * * E:first-child E is the first child of its parent
 * * E:last-child E is the last child of its parent
 * * E:nth-child(n) E is the nth child of its parent (1 based as per the spec)
 * * E:nth-child(odd) E is an odd child of its parent
 * * E:nth-child(even) E is an even child of its parent
 * * E:only-child E is the only child of its parent
 * * E:checked E is an element that is has a checked attribute that is true (e.g. a radio or checkbox)
 * * E:first the first E in the resultset
 * * E:last the last E in the resultset
 * * E:nth(n) the nth E in the resultset (1 based)
 * * E:odd shortcut for :nth-child(odd)
 * * E:even shortcut for :nth-child(even)
 * * E:not(S) an E element that does not match simple selector S
 * * E:has(S) an E element that has a descendant that matches simple selector S
 * * E:next(S) an E element whose next sibling matches simple selector S
 * * E:prev(S) an E element whose previous sibling matches simple selector S
 * * E:any(S1|S2|S2) an E element which matches any of the simple selectors S1, S2 or S3//\\
 *
 * ## CSS Value Selectors:
 *
 * * E{display=none} CSS value "display" that equals "none"
 * * E{display^=none} CSS value "display" that starts with "none"
 * * E{display$=none} CSS value "display" that ends with "none"
 * * E{display*=none} CSS value "display" that contains the substring "none"
 * * E{display%=2} CSS value "display" that is evenly divisible by 2
 * * E{display!=none} CSS value "display" that does not equal "none"

/**
 * @class Ext.DomHelper
 * @alternateClassName Ext.dom.Helper
 *
 * The DomHelper class provides a layer of abstraction from DOM and transparently supports creating elements via DOM or
 * using HTML fragments. It also has the ability to create HTML fragment templates from your DOM building code.
 *
 * ## DomHelper element specification object
 *
 * A specification object is used when creating elements. Attributes of this object are assumed to be element
 * attributes, except for 4 special attributes:
 *
 * * **tag**: The tag name of the element
 * * **children (or cn)**: An array of the same kind of element definition objects to be created and appended. These
 * can be nested as deep as you want.
 * * **cls**: The class attribute of the element. This will end up being either the "class" attribute on a HTML
 * fragment or className for a DOM node, depending on whether DomHelper is using fragments or DOM.
 * * **html**: The innerHTML for the element
 *
 * ## Insertion methods
 *
 * Commonly used insertion methods:
 *
 * * {@link #append}
 * * {@link #insertBefore}
 * * {@link #insertAfter}
 * * {@link #overwrite}
 * * {@link #insertHtml}
 *
 * ## Example
 *
 * This is an example, where an unordered list with 3 children items is appended to an existing element with id
 * 'my-div':
 *
 *     var dh = Ext.DomHelper; // create shorthand alias
 *     // specification object
 *     var spec = {
 *         id: 'my-ul',
 *         tag: 'ul',
 *         cls: 'my-list',
 *         // append children after creating
 *         children: [     // may also specify 'cn' instead of 'children'
 *             {tag: 'li', id: 'item0', html: 'List Item 0'},
 *             {tag: 'li', id: 'item1', html: 'List Item 1'},
 *             {tag: 'li', id: 'item2', html: 'List Item 2'}
 *         ]
 *     };
 *     var list = dh.append(
 *         'my-div', // the context element 'my-div' can either be the id or the actual node
 *         spec      // the specification object
 *     );
 *
 * Element creation specification parameters in this class may also be passed as an Array of specification objects.
 * This can be used to insert multiple sibling nodes into an existing container very efficiently. For example, to add
 * more list items to the example above:
 *
 *     dh.append('my-ul', [
 *         {tag: 'li', id: 'item3', html: 'List Item 3'},
 *         {tag: 'li', id: 'item4', html: 'List Item 4'}
 *     ]);
 *
 * ## Templating
 *
 * The real power is in the built-in templating. Instead of creating or appending any elements, createTemplate returns
 * a Template object which can be used over and over to insert new elements. Revisiting the example above, we could
 * utilize templating this time:
 *
 *     // create the node
 *     var list = dh.append('my-div', {tag: 'ul', cls: 'my-list'});
 *     // get template
 *     var tpl = dh.createTemplate({tag: 'li', id: 'item{0}', html: 'List Item {0}'});
 *
 *     for(var i = 0; i < 5; i++){
 *         tpl.append(list, i); // use template to append to the actual node
 *     }
 *
 * An example using a template:
 *
 *     var html = '"{0}" href="{1}" class="nav">{2}';
 *
 *     var tpl = new Ext.DomHelper.createTemplate(html);
 *     tpl.append('blog-roll', ['link1', 'http://www.tommymaintz.com/', "Tommy's Site"]);
 *     tpl.append('blog-roll', ['link2', 'http://www.avins.org/', "Jamie's Site"]);
 *
 * The same example using named parameters:
 *
 *     var html = '"{id}" href="{url}" class="nav">{text}';
 *
 *     var tpl = new Ext.DomHelper.createTemplate(html);
 *     tpl.append('blog-roll', {
 *         id: 'link1',
 *         url: 'http://www.tommymaintz.com/',
 *         text: "Tommy's Site"
 *     });
 *     tpl.append('blog-roll', {
 *         id: 'link2',
 *         url: 'http://www.avins.org/',
 *         text: "Jamie's Site"
 *     });
 *
 * ## Compiling Templates
 *
 * Templates are applied using regular expressions. The performance is great, but if you are adding a bunch of DOM
 * elements using the same template, you can increase performance even further by "compiling" the template. The way
 * "compile()" works is the template is parsed and broken up at the different variable points and a dynamic function is
 * created and eval'ed. The generated function performs string concatenation of these parts and the passed variables
 * instead of using regular expressions.
 *
 *     var html = '"{id}" href="{url}" class="nav">{text}';
 *
 *     var tpl = new Ext.DomHelper.createTemplate(html);
 *     tpl.compile();
 *
 *     // ... use template like normal
 *
 * ## Performance Boost
 *
 * DomHelper will transparently create HTML fragments when it can. Using HTML fragments instead of DOM can
 * significantly boost performance.
 *
 * Element creation specification parameters may also be strings. If useDom is false, then the string is used as
 * innerHTML. If useDom is true, a string specification results in the creation of a text node. Usage:
 *
 *     Ext.DomHelper.useDom = true; // force it to use DOM; reduces performance
 *

 *         },
 *
 *         quitJob: function() {
 *              this.fireEvent('quit');
 *         }
 *     });
 *
 *     var newEmployee = Ext.create('Employee', {
 *
 *         fullName: 'Ed Spencer',
 *
 *         listeners: {
 *             quit: function() { // This function will be called when the 'quit' event is fired
 *                 // By default, "this" will be the object that fired the event.
 *                 console.log(this.getFullName() + " has quit!");
 *             }

    /**
     * Appends an event handler to this object. You can review the available handlers by looking at the 'events'
     * section of the documentation for the component you are working with.
     *
     * ## Combining Options
     *
     * Using the options argument, it is possible to combine different types of listeners:
     *
     * A delayed, one-time listener:
     *
     *     container.on('tap', this.handleTap, this, {
     *         single: true,
     *         delay: 100
     *     });
     *
     * ## Attaching multiple handlers in 1 call
     *
     * The method also allows for a single argument to be passed which is a config object containing properties which
     * specify multiple events. For example:
     *
     *     container.on({
     *         tap  : this.onTap,
     *         swipe: this.onSwipe,
     *
     *         scope: this // Important. Ensure "this" is correct during handler execution
     *     });
     *
     * One can also specify options for each event handler separately:
     *
     *     container.on({
     *         tap  : { fn: this.onTap, scope: this, single: true },
     *         swipe: { fn: button.onSwipe, scope: button }
     *     });
     *
     * See the [Events Guide](#!/guide/events) for more.
     *
     * @param {String/String[]/Object} eventName The name of the event to listen for. May also be an object who's property names are
     * event names.
     * @param {Function} fn The method the event invokes.  Will be called with arguments given to
     * {@link #fireEvent} plus the `options` parameter described below.
     * @param {Object} [scope] The scope (`this` reference) in which the handler function is executed. **If
     * omitted, defaults to the object which fired the event.**
     * @param {Object} [options] An object containing handler configuration.
     *
     * This object may contain any of the following properties:

     * @param {Object} [options.scope] The scope (`this` reference) in which the handler function is executed. If omitted, defaults to the object
     * which fired the event.
     * @param {Number} [options.delay] The number of milliseconds to delay the invocation of the handler after the event fires.
     * @param {Boolean} [options.single] `true` to add a handler to handle just the next firing of the event, and then remove itself.
     * @param {String} [options.order=current] The order of when the listener should be added into the listener queue.
     *
     * If you set an order of `before` and the event you are listening to is preventable, you can return `false` and it will stop the event.
     *
     * Available options are `before`, `current` and `after`.
     *
     * @param {Number} [options.buffer] Causes the handler to be delayed by the specified number of milliseconds. If the event fires again within that
     * time, the original handler is _not_ invoked, but the new handler is scheduled in its place.
     * @param {String} [options.element] Allows you to add a listener onto a element of this component using the elements reference.
     *
     *     Ext.create('Ext.Component', {
     *         listeners: {
     *             element: 'element',
     *             tap: function() {
     *                 alert('element tap!');
     *             }
     *         }
     *     });

/**
 * @class Ext.Date

 * A set of useful static methods to deal with date.
 *
 * __Note:__ Unless you require `Ext.DateExtras`, only the {@link #now} method will be available. You **MUST**
 * require `Ext.DateExtras` to use the other methods available below.
 *
 * Usage with {@link Ext#setup}:
 *
 *     @example
 *     Ext.setup({
 *         requires: 'Ext.DateExtras',

 * The date parsing and formatting syntax contains a subset of
 * [PHP's `date()` function](http://www.php.net/date), and the formats that are
 * supported will provide results equivalent to their PHP versions.

                xindex = i2 + 1           // xindex is 1-based

/**
 * A template class that supports advanced functionality like:
 *
 * - Autofilling arrays using templates and sub-templates
 * - Conditional processing with basic comparison operators
 * - Basic math function support
 * - Execute arbitrary inline code with special built-in template variables
 * - Custom member functions
 * - Many special tags and built-in operators that aren't defined as part of the API, but are supported in the templates that can be created
 *
 * XTemplate provides the templating mechanism built into {@link Ext.DataView}.
 *
 * The {@link Ext.Template} describes the acceptable parameters to pass to the constructor. The following examples
 * demonstrate all of the supported features.
 *
 * # Sample Data
 *
 * This is the data object used for reference in each code example:
 *
 *     var data = {
 *         name: 'Don Griffin',
 *         title: 'Senior Technomage',
 *         company: 'Sencha Inc.',
 *         drinks: ['Coffee', 'Water', 'More Coffee'],
 *         kids: [
 *             { name: 'Aubrey',  age: 17 },
 *             { name: 'Joshua',  age: 13 },
 *             { name: 'Cale',    age: 10 },
 *             { name: 'Nikol',   age: 5 },
 *             { name: 'Solomon', age: 0 }
 *         ]
 *     };
 *
 * # Auto filling of arrays
 *
 * The **tpl** tag and the **for** operator are used to process the provided data object:
 *
 * - If the value specified in for is an array, it will auto-fill, repeating the template block inside the tpl
 *   tag for each item in the array.
 * - If for="." is specified, the data object provided is examined.
 * - While processing an array, the special variable {#} will provide the current array index + 1 (starts at 1, not 0).
 *
 * Examples:
 *
 *     <tpl for=".">...</tpl>       // loop through array at root node
 *     <tpl for="foo">...</tpl>     // loop through array at foo node
 *     <tpl for="foo.bar">...</tpl> // loop through array at foo.bar node
 *
 * Using the sample data above:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Kids: ',
 *         '<tpl for=".">',       // process the data.kids node
 *             '<p>{#}. {name}</p>',  // use current array index to autonumber
 *         '</tpl></p>'
 *     );
 *     tpl.overwrite(panel.body, data.kids); // pass the kids property of the data object
 *
 * An example illustrating how the **for** property can be leveraged to access specified members of the provided data
 * object to populate the template:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Title: {title}</p>',
 *         '<p>Company: {company}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',     // interrogate the kids property within the data
 *             '<p>{name}</p>',
 *         '</tpl></p>'
 *     );
 *     tpl.overwrite(panel.body, data);  // pass the root node of the data object
 *
 * Flat arrays that contain values (and not objects) can be auto-rendered using the special **`{.}`** variable inside a
 * loop. This variable will represent the value of the array at the current index:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>{name}\'s favorite beverages:</p>',
 *         '<tpl for="drinks">',
 *             '<div> - {.}</div>',
 *         '</tpl>'
 *     );
 *     tpl.overwrite(panel.body, data);
 *
 * When processing a sub-template, for example while looping through a child array, you can access the parent object's
 * members via the **parent** object:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',
 *             '<tpl if="age &gt; 1">',
 *                 '<p>{name}</p>',
 *                 '<p>Dad: {parent.name}</p>',
 *             '</tpl>',
 *         '</tpl></p>'
 *     );
 *     tpl.overwrite(panel.body, data);
 *
 * # Conditional processing with basic comparison operators
 *
 * The **tpl** tag and the **if** operator are used to provide conditional checks for deciding whether or not to render
 * specific parts of the template.
 *
 * Using the sample data above:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',
 *             '<tpl if="age &gt; 1">',
 *                 '<p>{name}</p>',
 *             '</tpl>',
 *         '</tpl></p>'
 *     );
 *     tpl.overwrite(panel.body, data);
 *
 * More advanced conditionals are also supported:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',
 *             '<p>{name} is a ',
 *             '<tpl if="age &gt;= 13">',
 *                 '<p>teenager</p>',
 *             '<tpl elseif="age &gt;= 2">',
 *                 '<p>kid</p>',
 *             '<tpl else>',
 *                 '<p>baby</p>',
 *             '</tpl>',
 *         '</tpl></p>'
 *     );
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',
 *             '<p>{name} is a ',
 *             '<tpl switch="name">',
 *                 '<tpl case="Aubrey" case="Nikol">',
 *                     '<p>girl</p>',
 *                 '<tpl default">',
 *                     '<p>boy</p>',
 *             '</tpl>',
 *         '</tpl></p>'
 *     );
 *
 * A `break` is implied between each case and default, however, multiple cases can be listed
 * in a single &lt;tpl&gt; tag.
 *
 * # Using double quotes
 *
 * Examples:
 *
 *     var tpl = new Ext.XTemplate(
 *         "<tpl if='age &gt; 1 && age &lt; 10'>Child</tpl>",
 *         "<tpl if='age &gt;= 10 && age &lt; 18'>Teenager</tpl>",
 *         "<tpl if='this.isGirl(name)'>...</tpl>",
 *         '<tpl if="id == \'download\'">...</tpl>',
 *         "<tpl if='needsIcon'><img src='{icon}' class='{iconCls}'/></tpl>",
 *         "<tpl if='name == \"Don\"'>Hello</tpl>"
 *     );
 *
 * # Basic math support
 *
 * The following basic math operators may be applied directly on numeric data values:
 *
 *     + - * /
 *
 * For example:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',
 *             '<tpl if="age &gt; 1">',  // <-- Note that the > is encoded
 *                 '<p>{#}: {name}</p>',  // <-- Auto-number each item
 *                 '<p>In 5 Years: {age+5}</p>',  // <-- Basic math
 *                 '<p>Dad: {parent.name}</p>',
 *             '</tpl>',
 *         '</tpl></p>'
 *     );
 *     tpl.overwrite(panel.body, data);
 *
 * # Execute arbitrary inline code with special built-in template variables
 *
 * Anything between `{[ ... ]}` is considered code to be executed in the scope of the template.
 * The expression is evaluated and the result is included in the generated result. There are
 * some special variables available in that code:
 *
 * - **out**: The output array into which the template is being appended (using `push` to later
 *   `join`).
 * - **values**: The values in the current scope. If you are using scope changing sub-templates,
 *   you can change what values is.
 * - **parent**: The scope (values) of the ancestor template.
 * - **xindex**: If you are in a looping template, the index of the loop you are in (1-based).
 * - **xcount**: If you are in a looping template, the total length of the array you are looping.
 *
 * This example demonstrates basic row striping using an inline code block and the xindex variable:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Company: {[values.company.toUpperCase() + ", " + values.title]}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',
 *             '<div class="{[xindex % 2 === 0 ? "even" : "odd"]}">',
 *             '{name}',
 *             '</div>',
 *         '</tpl></p>'
 *      );
 *
 * Any code contained in "verbatim" blocks (using "{% ... %}") will be inserted directly in
 * the generated code for the template. These blocks are not included in the output. This
 * can be used for simple things like break/continue in a loop, or control structures or
 * method calls (when they don't produce output). The `this` references the template instance.
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Company: {[values.company.toUpperCase() + ", " + values.title]}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',
 *             '{% if (xindex % 2 === 0) continue; %}',
 *             '{name}',
 *             '{% if (xindex > 100) break; %}',
 *             '</div>',
 *         '</tpl></p>'
 *      );
 *
 * # Template member functions
 *
 * One or more member functions can be specified in a configuration object passed into the XTemplate constructor for
 * more complex processing:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',
 *             '<tpl if="this.isGirl(name)">',
 *                 '<p>Girl: {name} - {age}</p>',
 *             '<tpl else>',
 *                 '<p>Boy: {name} - {age}</p>',
 *             '</tpl>',
 *             '<tpl if="this.isBaby(age)">',
 *                 '<p>{name} is a baby!</p>',
 *             '</tpl>',
 *         '</tpl></p>',
 *         {
 *             // XTemplate configuration:
 *             disableFormats: true,
 *             // member functions:
 *             isGirl: function(name){
 *                return name == 'Sara Grace';
 *             },
 *             isBaby: function(age){
 *                return age < 1;
 *             }
 *         }
 *     );
 *     tpl.overwrite(panel.body, data);

/**
 * Most of the visual classes you interact with in Sencha Touch are Components. Every Component in Sencha Touch is a
 * subclass of Ext.Component, which means they can all:
 *
 * * Render themselves onto the page using a template
 * * Show and hide themselves at any time
 * * Center themselves on the screen
 * * Enable and disable themselves
 *
 * They can also do a few more advanced things:
 *
 * * Float above other components (windows, message boxes and overlays)
 * * Change size and position on the screen with animation
 * * Dock other Components inside themselves (useful for toolbars)
 * * Align to other components, allow themselves to be dragged around, make their content scrollable & more
 *
 * ## Available Components
 *
 * There are many components available in Sencha Touch, separated into 4 main groups:
 *
 * ### Navigation components
 * * {@link Ext.Toolbar}
 * * {@link Ext.Button}
 * * {@link Ext.TitleBar}
 * * {@link Ext.SegmentedButton}
 * * {@link Ext.Title}
 * * {@link Ext.Spacer}
 *
 * ### Store-bound components
 * * {@link Ext.dataview.DataView}
 * * {@link Ext.Carousel}
 * * {@link Ext.List}
 * * {@link Ext.NestedList}
 *
 * ### Form components
 * * {@link Ext.form.Panel}
 * * {@link Ext.form.FieldSet}
 * * {@link Ext.field.Checkbox}
 * * {@link Ext.field.Hidden}
 * * {@link Ext.field.Slider}
 * * {@link Ext.field.Text}
 * * {@link Ext.picker.Picker}
 * * {@link Ext.picker.Date}
 *
 * ### General components
 * * {@link Ext.Panel}
 * * {@link Ext.tab.Panel}
 * * {@link Ext.Viewport Ext.Viewport}
 * * {@link Ext.Img}
 * * {@link Ext.Map}
 * * {@link Ext.Audio}
 * * {@link Ext.Video}
 * * {@link Ext.Sheet}
 * * {@link Ext.ActionSheet}
 * * {@link Ext.MessageBox}
 *
 *
 * ## Instantiating Components
 *
 * Components are created the same way as all other classes in Sencha Touch - using Ext.create. Here's how we can
 * create a Text field:
 *
 *     var panel = Ext.create('Ext.Panel', {
 *         html: 'This is my panel'
 *     });
 *
 * This will create a {@link Ext.Panel Panel} instance, configured with some basic HTML content. A Panel is just a
 * simple Component that can render HTML and also contain other items. In this case we've created a Panel instance but
 * it won't show up on the screen yet because items are not rendered immediately after being instantiated. This allows
 * us to create some components and move them around before rendering and laying them out, which is a good deal faster
 * than moving them after rendering.
 *
 * To show this panel on the screen now we can simply add it to the global Viewport:
 *
 *     Ext.Viewport.add(panel);
 *
 * Panels are also Containers, which means they can contain other Components, arranged by a layout. Let's revisit the
 * above example now, this time creating a panel with two child Components and a hbox layout:
 *
 *     @example
 *     var panel = Ext.create('Ext.Panel', {
 *         layout: 'hbox',
 *
 *         items: [
 *             {
 *                 xtype: 'panel',
 *                 flex: 1,
 *                 html: 'Left Panel, 1/3rd of total size',
 *                  style: 'background-color: #5E99CC;'
 *             },
 *             {
 *                 xtype: 'panel',
 *                 flex: 2,
 *                 html: 'Right Panel, 2/3rds of total size',
 *                  style: 'background-color: #759E60;'
 *             }
 *         ]
 *     });
 *
 *     Ext.Viewport.add(panel);
 *
 * This time we created 3 Panels - the first one is created just as before but the inner two are declared inline using
 * an xtype. Xtype is a convenient way of creating Components without having to go through the process of using
 * Ext.create and specifying the full class name, instead you can just provide the xtype for the class inside an object
 * and the framework will create the components for you.
 *
 * We also specified a layout for the top level panel - in this case hbox, which splits the horizontal width of the
 * parent panel based on the 'flex' of each child. For example, if the parent Panel above is 300px wide then the first
 * child will be flexed to 100px wide and the second to 200px because the first one was given `flex: 1` and the second
 * `flex: 2`.
 *
 * ## Using xtype
 *
 * xtype is an easy way to create Components without using the full class name. This is especially useful when creating
 * a {@link Ext.Container Container} that contains child Components. An xtype is simply a shorthand way of specifying a
 * Component - for example you can use `xtype: 'panel'` instead of typing out Ext.panel.Panel.
 *
 * Sample usage:
 *
 *     @example miniphone
 *     Ext.create('Ext.Container', {
 *         fullscreen: true,
 *         layout: 'fit',
 *
 *         items: [
 *             {
 *                 xtype: 'panel',
 *                 html: 'This panel is created by xtype'
 *             },
 *             {
 *                 xtype: 'toolbar',
 *                 title: 'So is the toolbar',
 *                 docked: 'top'
 *             }
 *         ]
 *     });
 *
 *
 * ### Common xtypes

 * Whenever you create a new Component you can pass in configuration options. All of the configurations for a given
 * Component are listed in the "Config options" section of its class docs page. You can pass in any number of
 * configuration options when you instantiate the Component, and modify any of them at any point later. For example, we
 * can easily modify the {@link Ext.Panel#html html content} of a Panel after creating it:
 *
 *     @example miniphone
 *     // we can configure the HTML when we instantiate the Component
 *     var panel = Ext.create('Ext.Panel', {
 *         fullscreen: true,
 *         html: 'This is a Panel'
 *     });
 *
 *     // we can update the HTML later using the setHtml method:
 *     panel.setHtml('Some new HTML');
 *
 *     // we can retrieve the current HTML using the getHtml method:
 *     Ext.Msg.alert(panel.getHtml()); // displays "Some new HTML"
 *
 * Every config has a getter method and a setter method - these are automatically generated and always follow the same
 * pattern. For example, a config called `html` will receive `getHtml` and `setHtml` methods, a config called `defaultType`
 * will receive `getDefaultType` and `setDefaultType` methods, and so on.
 *

 * See the [Component & Container Guide](#!/guide/components) for more information, and check out the
 * {@link Ext.Container} class docs also.

    /**
     * @cfg {String} xtype
     * The `xtype` configuration option can be used to optimize Component creation and rendering. It serves as a
     * shortcut to the full component name. For example, the component `Ext.button.Button` has an xtype of `button`.
     *
     * You can define your own xtype on a custom {@link Ext.Component component} by specifying the
     * {@link Ext.Class#alias alias} config option with a prefix of `widget`. For example:
     *
     *     Ext.define('PressMeButton', {
     *         extend: 'Ext.button.Button',
     *         alias: 'widget.pressmebutton',
     *         text: 'Press Me'
     *     });
     *
     * Any Component can be created implicitly as an object config with an xtype specified, allowing it to be
     * declared and passed into the rendering pipeline without actually being instantiated as an object. Not only is
     * rendering deferred, but the actual creation of the object itself is also deferred, saving memory and resources
     * until they are actually needed. In complex, nested layouts containing many Components, this can make a
     * noticeable improvement in performance.
     *
     *     // Explicit creation of contained Components:
     *     var panel = new Ext.Panel({
     *        // ...
     *        items: [
     *           Ext.create('Ext.button.Button', {
     *              text: 'OK'
     *           })
     *        ]
     *     });
     *
     *     // Implicit creation using xtype:
     *     var panel = new Ext.Panel({
     *        // ...
     *        items: [{
     *           xtype: 'button',
     *           text: 'OK'
     *        }]
     *     });
     *
     * In the first example, the button will always be created immediately during the panel's initialization. With
     * many added Components, this approach could potentially slow the rendering of the page. In the second example,
     * the button will not be created or rendered until the panel is actually displayed in the browser. If the panel
     * is never displayed (for example, if it is a tab that remains hidden) then the button will never be created and
     * will never consume any resources whatsoever.

/**
 * @aside guide layouts
 * @aside video layouts
 *
 * Sometimes you want to show several screens worth of information but you've only got a small screen to work with.
 * TabPanels and Carousels both enable you to see one screen of many at a time, and underneath they both use a Card
 * Layout.
 *
 * Card Layout takes the size of the Container it is applied to and sizes the currently active item to fill the
 * Container completely. It then hides the rest of the items, allowing you to change which one is currently visible but
 * only showing one at once:
 *
 * {@img ../guides/layouts/card.jpg}
 *
 *
 * Here the gray box is our Container, and the blue box inside it is the currently active card. The three other cards
 * are hidden from view, but can be swapped in later. While it's not too common to create Card layouts directly, you
 * can do so like this:
 *
 *     var panel = Ext.create('Ext.Panel', {
 *         layout: 'card',
 *         items: [
 *             {
 *                 html: "First Item"
 *             },
 *             {
 *                 html: "Second Item"
 *             },
 *             {
 *                 html: "Third Item"
 *             },
 *             {
 *                 html: "Fourth Item"
 *             }
 *         ]
 *     });
 *
 *     panel.{@link Ext.Container#setActiveItem setActiveItem}(1);
 *
 * Here we create a Panel with a Card Layout and later set the second item active (the active item index is zero-based,
 * so 1 corresponds to the second item). Normally you're better off using a {@link Ext.tab.Panel tab panel} or a
 * {@link Ext.carousel.Carousel carousel}.
 *
 * For a more detailed overview of what layouts are and the types of layouts shipped with Sencha Touch 2, check out the
 * [Layout Guide](#!/guide/layouts).

/**
 * @class Ext.scroll.Scroller
 * @author Jacky Nguyen <jacky@sencha.com>
 *
 * Momentum scrolling is one of the most important part of the framework's UI layer. In Sencha Touch there are
 * several scroller implementations so we can have the best performance on all mobile devices and browsers.
 *
 * Scroller settings can be changed using the {@link Ext.Container#scrollable scrollable} configuration in
 * {@link Ext.Container}. Anything you pass to that method will be passed to the scroller when it is
 * instantiated in your container.
 *
 * Please note that the {@link Ext.Container#getScrollable} method returns an instance of {@link Ext.scroll.View}.
 * So if you need to get access to the scroller after your container has been instantiated, you must used the
 * {@link Ext.scroll.View#getScroller} method.
 *
 *     // lets assume container is a container you have
 *     // created which is scrollable
 *     container.getScrollable().getScroller().setFps(10);
 *
 * ## Example
 *
 * Here is a simple example of how to adjust the scroller settings when using a {@link Ext.Container} (or anything
 * that extends it).
 *
 *     @example
 *     var container = Ext.create('Ext.Container', {
 *         fullscreen: true,
 *         html: 'This container is scrollable!',
 *         scrollable: {
 *             direction: 'vertical'
 *         }
 *     });
 *
 * As you can see, we are passing the {@link #direction} configuration into the scroller instance in our container.
 *
 * You can pass any of the configs below in that {@link Ext.Container#scrollable scrollable} configuration and it will
 * just work.
 *
 * Go ahead and try it in the live code editor above!

/**
 * A Container has all of the abilities of {@link Ext.Component Component}, but lets you nest other Components inside
 * it. Applications are made up of lots of components, usually nested inside one another. Containers allow you to
 * render and arrange child Components inside them. Most apps have a single top-level Container called a Viewport,
 * which takes up the entire screen. Inside of this are child components, for example in a mail app the Viewport
 * Container's two children might be a message List and an email preview pane.
 *
 * Containers give the following extra functionality:
 *
 * - Adding child Components at instantiation and run time
 * - Removing child Components
 * - Specifying a [Layout](#!/guide/layouts)
 *
 * Layouts determine how the child Components should be laid out on the screen. In our mail app example we'd use an
 * HBox layout so that we can pin the email list to the left hand edge of the screen and allow the preview pane to
 * occupy the rest. There are several layouts in Sencha Touch 2, each of which help you achieve your desired
 * application structure, further explained in the [Layout guide](#!/guide/layouts).
 *
 * ## Adding Components to Containers
 *
 * As we mentioned above, Containers are special Components that can have child Components arranged by a Layout. One of
 * the code samples above showed how to create a Panel with 2 child Panels already defined inside it but it's easy to
 * do this at run time too:
 *
 *     @example miniphone
 *     //this is the Panel we'll be adding below
 *     var aboutPanel = Ext.create('Ext.Panel', {
 *         html: 'About this app'
 *     });
 *
 *     //this is the Panel we'll be adding to
 *     var mainPanel = Ext.create('Ext.Panel', {
 *         fullscreen: true,
 *
 *         layout: 'hbox',
 *         defaults: {
 *             flex: 1
 *         },
 *
 *         items: {
 *             html: 'First Panel',
 *             style: 'background-color: #5E99CC;'
 *         }
 *     });
 *
 *     //now we add the first panel inside the second
 *     mainPanel.add(aboutPanel);
 *
 * Here we created three Panels in total. First we made the aboutPanel, which we might use to tell the user a little
 * about the app. Then we create one called mainPanel, which already contains a third Panel in its
 * {@link Ext.Container#cfg-items items} configuration, with some dummy text ("First Panel"). Finally, we add the first
 * panel to the second by calling the {@link Ext.Container#method-add add} method on `mainPanel`.
 *
 * In this case we gave our mainPanel another hbox layout, but we also introduced some
 * {@link Ext.Container#defaults defaults}. These are applied to every item in the Panel, so in this case every child
 * inside `mainPanel` will be given a `flex: 1` configuration. The effect of this is that when we first render the screen
 * only a single child is present inside `mainPanel`, so that child takes up the full width available to it. Once the
 * `mainPanel.add` line is called though, the `aboutPanel` is rendered inside of it and also given a `flex` of 1, which will
 * cause it and the first panel to both receive half the full width of the `mainPanel`.
 *
 * Likewise, it's easy to remove items from a Container:
 *
 *     mainPanel.remove(aboutPanel);
 *
 * After this line is run everything is back to how it was, with the first child panel once again taking up the full
 * width inside `mainPanel`.
 *
 * ## Further Reading
 *
 * See the [Component & Container Guide](#!/guide/components) for more information, and check out the
 * {@link Ext.Container} class docs also.

/**
 * A simple class to display a button in Sencha Touch.
 *
 * There are various different styles of Button you can create by using the {@link #icon},
 * {@link #iconCls}, {@link #iconAlign}, {@link #iconMask}, {@link #ui}, and {@link #text}
 * configurations.
 *
 * ## Simple Button
 *
 * Here is a Button in it's simplest form:
 *
 *     @example miniphone
 *     var button = Ext.create('Ext.Button', {
 *         text: 'Button'
 *     });
 *     Ext.Viewport.add({ xtype: 'container', padding: 10, items: [button] });
 *
 * ## Icons
 *
 * You can also create a Button with just an icon using the {@link #iconCls} configuration:
 *
 *     @example miniphone
 *     var button = Ext.create('Ext.Button', {
 *         iconCls: 'refresh',
 *         iconMask: true
 *     });
 *     Ext.Viewport.add({ xtype: 'container', padding: 10, items: [button] });
 *
 * Note that the {@link #iconMask} configuration is required when you want to use any of the
 * bundled Pictos icons.
 *
 * Here are the included icons available (if {@link Global_CSS#$include-default-icons $include-default-icons}
 * is set to `true`):

 *
 * You can also use other pictos icons by using the {@link Global_CSS#pictos-iconmask pictos-iconmask} mixin in your Sass.
 *
 * ## Badges
 *
 * Buttons can also have a badge on them, by using the {@link #badgeText} configuration:
 *
 *     @example
 *     Ext.create('Ext.Container', {
 *         fullscreen: true,
 *         padding: 10,
 *         items: {
 *             xtype: 'button',
 *             text: 'My Button',
 *             badgeText: '2'
 *         }
 *     });
 *
 * ## UI
 *
 * Buttons also come with a range of different default UIs. Here are the included UIs
 * available (if {@link #$include-button-uis $include-button-uis} is set to `true`):
 *
 * - **normal** - a basic gray button
 * - **back** - a back button
 * - **forward** - a forward button
 * - **round** - a round button
 * - **action** - shaded using the {@link Global_CSS#$active-color $active-color} (dark blue by default)
 * - **decline** - shaded using the {@link Global_CSS#$alert-color $alert-color} (red by default)
 * - **confirm** - shaded using the {@link Global_CSS#$confirm-color $confirm-color} (green by default)
 *
 * And setting them is very simple:
 *
 *     var uiButton = Ext.create('Ext.Button', {
 *         text: 'My Button',
 *         ui: 'action'
 *     });
 *
 * And how they look:
 *
 *     @example miniphone preview
 *     Ext.create('Ext.Container', {
 *         fullscreen: true,
 *         padding: 4,
 *         defaults: {
 *             xtype: 'button',
 *             margin: 5
 *         },
 *         layout: {
 *             type: 'vbox',
 *             align: 'center'
 *         },
 *         items: [
 *             { ui: 'normal', text: 'normal' },
 *             { ui: 'round', text: 'round' },
 *             { ui: 'action', text: 'action' },
 *             { ui: 'decline', text: 'decline' },
 *             { ui: 'confirm', text: 'confirm' }
 *         ]
 *     });
 *
 * Note that the default {@link #ui} is **normal**.
 *
 * You can also use the {@link #sencha-button-ui sencha-button-ui} CSS Mixin to create your own UIs.
 *
 * ## Example
 *
 * This example shows a bunch of icons on the screen in two toolbars. When you click on the center
 * button, it switches the {@link #iconCls} on every button on the page.
 *
 *     @example preview
 *     Ext.createWidget('container', {
 *         fullscreen: true,
 *         layout: {
 *             type: 'vbox',
 *             pack:'center',
 *             align: 'center'
 *         },
 *         items: [
 *             {
 *                 xtype: 'button',
 *                 text: 'Change iconCls',
 *                 handler: function() {

/**
 * {@link Ext.ActionSheet ActionSheets} are used to display a list of {@link Ext.Button buttons} in a popup dialog.
 *
 * The key difference between ActionSheet and {@link Ext.Sheet} is that ActionSheets are docked at the bottom of the
 * screen, and the {@link #defaultType} is set to {@link Ext.Button button}.
 *
 * ## Example
 *
 *     @example preview miniphone
 *     var actionSheet = Ext.create('Ext.ActionSheet', {
 *         items: [
 *             {
 *                 text: 'Delete draft',
 *                 ui  : 'decline'
 *             },
 *             {
 *                 text: 'Save draft'
 *             },
 *             {
 *                 text: 'Cancel',
 *                 ui  : 'confirm'
 *             }
 *         ]
 *     });
 *
 *     Ext.Viewport.add(actionSheet);
 *     actionSheet.show();
 *
 * As you can see from the code above, you no longer have to specify a `xtype` when creating buttons within a {@link Ext.ActionSheet ActionSheet},
 * because the {@link #defaultType} is set to {@link Ext.Button button}.

/**
 * The Connection class encapsulates a connection to the page's originating domain, allowing requests to be made either
 * to a configured URL, or to a URL specified at request time.
 *
 * Requests made by this class are asynchronous, and will return immediately. No data from the server will be available
 * to the statement immediately following the {@link #request} call. To process returned data, use a success callback
 * in the request options object, or an {@link #requestcomplete event listener}.
 *
 * # File Uploads
 *
 * File uploads are not performed using normal "Ajax" techniques, that is they are not performed using XMLHttpRequests.
 * Instead the form is submitted in the standard manner with the DOM `<form>` element temporarily modified to have its
 * target set to refer to a dynamically generated, hidden `<iframe>` which is inserted into the document but removed
 * after the return data has been gathered.
 *
 * The server response is parsed by the browser to create the document for the IFRAME. If the server is using JSON to
 * send the return object, then the Content-Type header must be set to "text/html" in order to tell the browser to
 * insert the text unchanged into the document body.
 *
 * Characters which are significant to an HTML parser must be sent as HTML entities, so encode `<` as `&lt;`, `&` as
 * `&amp;` etc.
 *
 * The response text is retrieved from the document, and a fake XMLHttpRequest object is created containing a
 * responseText property in order to conform to the requirements of event handlers and callbacks.
 *
 * Be aware that file upload packets are sent with the content type multipart/form and some server technologies
 * (notably JEE) may require some custom processing in order to retrieve parameter names and parameter values from the
 * packet content.
 *
 * __Note:__ It is not possible to check the response code of the hidden iframe, so the success handler will _always_ fire.

/**
 * {@link Ext.Audio} is a simple class which provides a container for the [HTML5 Audio element](http://developer.mozilla.org/en-US/docs/Using_HTML5_audio_and_video).
 *
 * ## Recommended File Types/Compression:
 * * Uncompressed WAV and AIF audio
 * * MP3 audio
 * * AAC-LC
 * * HE-AAC audio
 *
 * ## Notes
 * On Android devices, the audio tags controls do not show. You must use the {@link #method-play}, {@link #method-pause} and
 * {@link #toggle} methods to control the audio (example below).
 *
 * ## Examples
 *
 * Here is an example of the {@link Ext.Audio} component in a fullscreen container:
 *
 *     @example preview
 *     Ext.create('Ext.Container', {
 *         fullscreen: true,

 *
 * Provides searching of Components within {@link Ext.ComponentManager} (globally) or a specific
 * {@link Ext.Container} on the document with a similar syntax to a CSS selector.
 *
 * Components can be retrieved by using their {@link Ext.Component xtype} with an optional '.' prefix
 *
 * - `component` or `.component`
 * - `gridpanel` or `.gridpanel`
 *
 * An itemId or id must be prefixed with a #
 *
 * - `#myContainer`
 *
 * Attributes must be wrapped in brackets
 *
 * - `component[autoScroll]`
 * - `panel[title="Test"]`
 *
 * Member expressions from candidate Components may be tested. If the expression returns a *truthy* value,
 * the candidate Component will be included in the query:
 *
 *     var disabledFields = myFormPanel.query("{isDisabled()}");
 *
 * Pseudo classes may be used to filter results in the same way as in {@link Ext.DomQuery DomQuery}:
 *
 *     // Function receives array and returns a filtered array.
 *     Ext.ComponentQuery.pseudos.invalid = function(items) {
 *         var i = 0, l = items.length, c, result = [];

 *                 result.push(c);
 *             }
 *         }
 *         return result;
 *     };
 *
 *     var invalidFields = myFormPanel.query('field:invalid');
 *     if (invalidFields.length) {
 *         invalidFields[0].getEl().scrollIntoView(myFormPanel.body);
 *         for (var i = 0, l = invalidFields.length; i < l; i++) {
 *             invalidFields[i].getEl().frame("red");
 *         }
 *     }
 *
 * Default pseudos include:
 *
 * - not
 *
 * Queries return an array of components.
 * Here are some example queries.
 *
 *     // retrieve all Ext.Panels in the document by xtype
 *     var panelsArray = Ext.ComponentQuery.query('panel');
 *
 *     // retrieve all Ext.Panels within the container with an id myCt
 *     var panelsWithinmyCt = Ext.ComponentQuery.query('#myCt panel');
 *
 *     // retrieve all direct children which are Ext.Panels within myCt
 *     var directChildPanel = Ext.ComponentQuery.query('#myCt > panel');
 *
 *     // retrieve all grids and trees
 *     var gridsAndTrees = Ext.ComponentQuery.query('gridpanel, treepanel');

 * {@link Ext.Container#down} and {@link Ext.Container#child} methods. Also see

/**
 * @class Ext.Decorator
 * @extends Ext.Component
 *
 * In a few words, a Decorator is a Component that wraps around another Component. A typical example of a Decorator is a
 * {@link Ext.field.Field Field}. A form field is nothing more than a decorator around another component, and gives the
 * component a label, as well as extra styling to make it look good in a form.
 *
 * A Decorator can be thought of as a lightweight Container that has only one child item, and no layout overhead.
 * The look and feel of decorators can be styled purely in CSS.
 *
 * Another powerful feature that Decorator provides is config proxying. For example: all config items of a
 * {@link Ext.slider.Slider Slider} also exist in a {@link Ext.field.Slider Slider Field} for API convenience.
 * The {@link Ext.field.Slider Slider Field} simply proxies all corresponding getters and setters
 * to the actual {@link Ext.slider.Slider Slider} instance. Writing out all the setters and getters to do that is a tedious task
 * and a waste of code space. Instead, when you sub-class Ext.Decorator, all you need to do is to specify those config items
 * that you want to proxy to the Component using a special 'proxyConfig' class property. Here's how it may look like
 * in a Slider Field class:
 *
 *     Ext.define('My.field.Slider', {
 *         extend: 'Ext.Decorator',
 *
 *         config: {
 *             component: {
 *                 xtype: 'slider'
 *             }
 *         },
 *
 *         proxyConfig: {
 *             minValue: 0,
 *             maxValue: 100,
 *             increment: 1
 *         }
 *
 *         // ...
 *     });
 *
 * Once `My.field.Slider` class is created, it will have all setters and getters methods for all items listed in `proxyConfig`
 * automatically generated. These methods all proxy to the same method names that exist within the Component instance.

/**
 * This is a simple way to add an image of any size to your application and have it participate in the layout system
 * like any other component. This component typically takes between 1 and 3 configurations - a {@link #src}, and
 * optionally a {@link #height} and a {@link #width}:
 *
 *     @example miniphone
 *     var img = Ext.create('Ext.Img', {
 *         src: 'http://www.sencha.com/assets/images/sencha-avatar-64x64.png',
 *         height: 64,
 *         width: 64
 *     });
 *     Ext.Viewport.add(img);
 *
 * It's also easy to add an image into a panel or other container using its xtype:
 *
 *     @example miniphone
 *     Ext.create('Ext.Panel', {
 *         fullscreen: true,
 *         layout: 'hbox',
 *         items: [
 *             {
 *                 xtype: 'image',
 *                 src: 'http://www.sencha.com/assets/images/sencha-avatar-64x64.png',
 *                 flex: 1
 *             },
 *             {
 *                 xtype: 'panel',
 *                 flex: 2,
 *                 html: 'Sencha Inc.<br/>1700 Seaport Boulevard Suite 120, Redwood City, CA'
 *             }
 *         ]
 *     });
 *
 * Here we created a panel which contains an image (a profile picture in this case) and a text area to allow the user
 * to enter profile information about themselves. In this case we used an {@link Ext.layout.HBox hbox layout} and
 * flexed the image to take up one third of the width and the text area to take two thirds of the width. See the
 * {@link Ext.layout.HBox hbox docs} for more information on flexing items.

The {@link Ext.Spacer} component is generally used to put space between items in {@link Ext.Toolbar} components.

## Examples

By default the {@link #flex} configuration is set to 1:

    @example miniphone preview
    Ext.create('Ext.Container', {
        fullscreen: true,
        items: [
            {
                xtype : 'toolbar',
                docked: 'top',
                items: [
                    {
                        xtype: 'button',
                        text : 'Button One'
                    },
                    {
                        xtype: 'spacer'
                    },
                    {
                        xtype: 'button',
                        text : 'Button Two'
                    }
                ]
            }
        ]
    });

Alternatively you can just set the {@link #width} configuration which will get the {@link Ext.Spacer} a fixed width:

        layout: {
            type: 'vbox',
            pack: 'center',

        },
        items: [
            {
                xtype : 'toolbar',
                docked: 'top',
                items: [
                    {
                        xtype: 'button',
                        text : 'Button One'
                    },
                    {
                        xtype: 'spacer',
                        width: 50
                    },

/**
 * @aside video tabs-toolbars
 *
 * {@link Ext.Toolbar}s are most commonly used as docked items as within a {@link Ext.Container}. They can be docked either `top` or `bottom` using the {@link #docked} configuration.
 *
 * They allow you to insert items (normally {@link Ext.Button buttons}) and also add a {@link #title}.
 *
 * The {@link #defaultType} of {@link Ext.Toolbar} is {@link Ext.Button}.
 *
 * You can alternatively use {@link Ext.TitleBar} if you want the title to automatically adjust the size of its items.
 *
 * ## Examples
 *
 *     @example miniphone preview
 *     Ext.create('Ext.Container', {
 *         fullscreen: true,
 *         layout: {
 *             type: 'vbox',

 *
 * ## Notes
 *
 * You must use a HTML5 doctype for {@link #docked} `bottom` to work. To do this, simply add the following code to the HTML file:
 *
 *     <!doctype html>
 *
 * So your index.html file should look a little like this:
 *
 *     <!doctype html>
 *     <html>
 *         <head>
 *             <title>MY application title</title>
 *             ...

/**
 * @aside guide forms
 *
 * Field is the base class for all form fields used in Sencha Touch. It provides a lot of shared functionality to all
 * field subclasses (for example labels, simple validation, {@link #clearIcon clearing} and tab index management), but
 * is rarely used directly. Instead, it is much more common to use one of the field subclasses:
 *
 *     xtype            Class
 *     ---------------------------------------
 *     textfield        {@link Ext.field.Text}
 *     numberfield      {@link Ext.field.Number}
 *     textareafield    {@link Ext.field.TextArea}
 *     hiddenfield      {@link Ext.field.Hidden}
 *     radiofield       {@link Ext.field.Radio}
 *     checkboxfield    {@link Ext.field.Checkbox}
 *     selectfield      {@link Ext.field.Select}
 *     togglefield      {@link Ext.field.Toggle}
 *     fieldset         {@link Ext.form.FieldSet}
 *
 * Fields are normally used within the context of a form and/or fieldset. See the {@link Ext.form.Panel FormPanel}
 * and {@link Ext.form.FieldSet FieldSet} docs for examples on how to put those together, or the list of links above
 * for usage of individual field types. If you wish to create your own Field subclasses you can extend this class,
 * though it is sometimes more useful to extend {@link Ext.field.Text} as this provides additional text entry
 * functionality.

/**
 * @aside guide forms
 *
 * The text field is the basis for most of the input fields in Sencha Touch. It provides a baseline of shared
 * functionality such as input validation, standard events, state management and look and feel. Typically we create
 * text fields inside a form, like this:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 title: 'Enter your name',
 *                 items: [
 *                     {
 *                         xtype: 'textfield',
 *                         label: 'First Name',
 *                         name: 'firstName'
 *                     },
 *                     {
 *                         xtype: 'textfield',
 *                         label: 'Last Name',
 *                         name: 'lastName'
 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * This creates two text fields inside a form. Text Fields can also be created outside of a Form, like this:
 *
 *     Ext.create('Ext.field.Text', {
 *         label: 'Your Name',
 *         value: 'Ed Spencer'
 *     });
 *
 * ## Configuring
 *
 * Text field offers several configuration options, including {@link #placeHolder}, {@link #maxLength},
 * {@link #autoComplete}, {@link #autoCapitalize} and {@link #autoCorrect}. For example, here is how we would configure
 * a text field to have a maximum length of 10 characters, with placeholder text that disappears when the field is
 * focused:
 *
 *     Ext.create('Ext.field.Text', {
 *         label: 'Username',
 *         maxLength: 10,
 *         placeHolder: 'Enter your username'
 *     });
 *
 * The autoComplete, autoCapitalize and autoCorrect configs simply set those attributes on the text field and allow the
 * native browser to provide those capabilities. For example, to enable auto complete and auto correct, simply
 * configure your text field like this:
 *
 *     Ext.create('Ext.field.Text', {
 *         label: 'Username',
 *         autoComplete: true,
 *         autoCorrect: true
 *     });
 *
 * These configurations will be picked up by the native browser, which will enable the options at the OS level.
 *
 * Text field inherits from {@link Ext.field.Field}, which is the base class for all fields in Sencha Touch and provides
 * a lot of shared functionality for all fields, including setting values, clearing and basic validation. See the
 * {@link Ext.field.Field} documentation to see how to leverage its capabilities.

/**
 * @aside guide forms
 *
 * Creates an HTML textarea field on the page. This is useful whenever you need the user to enter large amounts of text
 * (i.e. more than a few words). Typically, text entry on mobile devices is not a pleasant experience for the user so
 * it's good to limit your use of text areas to only those occasions when free form text is required or alternative
 * input methods like select boxes or radio buttons are not possible. Text Areas are usually created inside forms, like
 * this:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 title: 'About you',
 *                 items: [
 *                     {
 *                         xtype: 'textfield',
 *                         label: 'Name',
 *                         name: 'name'
 *                     },
 *                     {
 *                         xtype: 'textareafield',
 *                         label: 'Bio',
 *                         maxRows: 4,
 *                         name: 'bio'
 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * In the example above we're creating a form with a {@link Ext.field.Text text field} for the user's name and a text
 * area for their bio. We used the {@link #maxRows} configuration on the text area to tell it to grow to a maximum of 4
 * rows of text before it starts using a scroll bar inside the text area to scroll the text.
 *
 * We can also create a text area outside the context of a form, like this:
 *
 * This creates two text fields inside a form. Text Fields can also be created outside of a Form, like this:
 *
 *     Ext.create('Ext.field.TextArea', {
 *         label: 'About You',
 *         {@link #placeHolder}: 'Tell us about yourself...'
 *     });

 * for the {@link #method-show show} method for more details).
 *
 *     @example preview

         * ### Confirm
         * Use the {@link #confirm} method to show a confirmation alert (shows yes and no buttons).
         *
         *     @example preview
         *     Ext.Msg.confirm("Confirmation", "Are you sure you want to do that?", Ext.emptyFn);

/**
 * {@link Ext.TitleBar}'s are most commonly used as a docked item within an {@link Ext.Container}.
 *
 * The main difference between a {@link Ext.TitleBar} and an {@link Ext.Toolbar} is that
 * the {@link #title} configuration is **always** centered horizontally in a {@link Ext.TitleBar} between
 * any items aligned left or right.
 *
 * You can also give items of a {@link Ext.TitleBar} an `align` configuration of `left` or `right`
 * which will dock them to the `left` or `right` of the bar.
 *
 * ## Examples
 *
 *     @example preview
 *     Ext.Viewport.add({
 *         xtype: 'titlebar',
 *         docked: 'top',
 *         title: 'Navigation',
 *         items: [
 *             {
 *                 iconCls: 'add',
 *                 iconMask: true,
 *                 align: 'left'
 *             },
 *             {
 *                 iconCls: 'home',
 *                 iconMask: true,
 *                 align: 'right'
 *             }
 *         ]
 *     });
 *
 *     Ext.Viewport.setStyleHtmlContent(true);
 *     Ext.Viewport.setHtml('This shows the title being centered and buttons using align <i>left</i> and <i>right</i>.');
 *
 * <br />
 *
 *     @example preview
 *     Ext.Viewport.add({
 *         xtype: 'titlebar',
 *         docked: 'top',
 *         title: 'Navigation',
 *         items: [
 *             {
 *                 align: 'left',

 *                 align: 'right'
 *             }
 *         ]
 *     });
 *
 *     Ext.Viewport.setStyleHtmlContent(true);
 *     Ext.Viewport.setHtml('This shows how the title is automatically moved to the right when one of the aligned buttons is very wide.');

 *                 text: 'This button has a super long title'
 *             },
 *             {
 *                 align: 'right',

/**
 * @aside example video
 * Provides a simple Container for HTML5 Video.
 *
 * ## Notes
 *
 * - There are quite a few issues with the `<video>` tag on Android devices. On Android 2+, the video will
 * appear and play on first attempt, but any attempt afterwards will not work.
 *
 * ## Useful Properties
 *
 * - {@link #url}
 * - {@link #autoPause}
 * - {@link #autoResume}
 *
 * ## Useful Methods
 *
 * - {@link #method-pause}
 * - {@link #method-play}
 * - {@link #toggle}
 *
 * ## Example
 *
 *     var panel = Ext.create('Ext.Panel', {

 *
 * Controllers are responsible for responding to events that occur within your app. If your app contains a Logout
 * {@link Ext.Button button} that your user can tap on, a Controller would listen to the Button's tap event and take
 * the appropriate action. It allows the View classes to handle the display of data and the Model classes to handle the
 * loading and saving of data - the Controller is the glue that binds them together.
 *
 * ## Relation to Ext.app.Application
 *
 * Controllers exist within the context of an {@link Ext.app.Application Application}. An Application usually consists
 * of a number of Controllers, each of which handle a specific part of the app. For example, an Application that
 * handles the orders for an online shopping site might have controllers for Orders, Customers and Products.
 *
 * All of the Controllers that an Application uses are specified in the Application's
 * {@link Ext.app.Application#controllers} config. The Application automatically instantiates each Controller and keeps
 * references to each, so it is unusual to need to instantiate Controllers directly. By convention each Controller is
 * named after the thing (usually the Model) that it deals with primarily, usually in the plural - for example if your
 * app is called 'MyApp' and you have a Controller that manages Products, convention is to create a
 * MyApp.controller.Products class in the file app/controller/Products.js.
 *
 * ## Refs and Control
 *
 * The centerpiece of Controllers is the twin configurations {@link #refs} and {@link #cfg-control}. These are used to
 * easily gain references to Components inside your app and to take action on them based on events that they fire.
 * Let's look at {@link #refs} first:
 *
 * ### Refs
 *
 * Refs leverage the powerful {@link Ext.ComponentQuery ComponentQuery} syntax to easily locate Components on your
 * page. We can define as many refs as we like for each Controller, for example here we define a ref called 'nav' that
 * finds a Component on the page with the ID 'mainNav'. We then use that ref in the addLogoutButton beneath it:
 *
 *     Ext.define('MyApp.controller.Main', {
 *         extend: 'Ext.app.Controller',
 *
 *         config: {
 *             refs: {
 *                 nav: '#mainNav'
 *             }
 *         },
 *
 *         addLogoutButton: function() {
 *             this.getNav().add({
 *                 text: 'Logout'
 *             });
 *         }
 *     });
 *
 * Usually, a ref is just a key/value pair - the key ('nav' in this case) is the name of the reference that will be
 * generated, the value ('#mainNav' in this case) is the {@link Ext.ComponentQuery ComponentQuery} selector that will
 * be used to find the Component.
 *
 * Underneath that, we have created a simple function called addLogoutButton which uses this ref via its generated
 * 'getNav' function. These getter functions are generated based on the refs you define and always follow the same
 * format - 'get' followed by the capitalized ref name. In this case we're treating the nav reference as though it's a
 * {@link Ext.Toolbar Toolbar}, and adding a Logout button to it when our function is called. This ref would recognize
 * a Toolbar like this:
 *
 *     Ext.create('Ext.Toolbar', {
 *         id: 'mainNav',
 *
 *         items: [
 *             {
 *                 text: 'Some Button'
 *             }
 *         ]
 *     });
 *
 * Assuming this Toolbar has already been created by the time we run our 'addLogoutButton' function (we'll see how that
 * is invoked later), it will get the second button added to it.
 *
 * ### Advanced Refs
 *
 * Refs can also be passed a couple of additional options, beyond name and selector. These are autoCreate and xtype,
 * which are almost always used together:
 *
 *     Ext.define('MyApp.controller.Main', {
 *         extend: 'Ext.app.Controller',
 *
 *         config: {
 *             refs: {
 *                 nav: '#mainNav',
 *
 *                 infoPanel: {
 *                     selector: 'tabpanel panel[name=fish] infopanel',
 *                     xtype: 'infopanel',
 *                     autoCreate: true
 *                 }
 *             }
 *         }
 *     });
 *
 * We've added a second ref to our Controller. Again the name is the key, 'infoPanel' in this case, but this time we've
 * passed an object as the value instead. This time we've used a slightly more complex selector query - in this example
 * imagine that your app contains a {@link Ext.tab.Panel tab panel} and that one of the items in the tab panel has been
 * given the name 'fish'. Our selector matches any Component with the xtype 'infopanel' inside that tab panel item.
 *
 * The difference here is that if that infopanel does not exist already inside the 'fish' panel, it will be
 * automatically created when you call this.getInfoPanel inside your Controller. The Controller is able to do this
 * because we provided the xtype to instantiate with in the event that the selector did not return anything.
 *
 * ### Control
 *
 * The sister config to {@link #refs} is {@link #cfg-control}. {@link #cfg-control Control} is the means by which your listen
 * to events fired by Components and have your Controller react in some way. Control accepts both ComponentQuery
 * selectors and refs as its keys, and listener objects as values - for example:
 *
 *     Ext.define('MyApp.controller.Main', {
 *         extend: 'Ext.app.Controller',
 *
 *         config: {
 *             control: {
 *                 loginButton: {
 *                     tap: 'doLogin'
 *                 },
 *                 'button[action=logout]': {
 *                     tap: 'doLogout'
 *                 }
 *             },
 *
 *             refs: {
 *                 loginButton: 'button[action=login]'
 *             }
 *         },
 *
 *         doLogin: function() {
 *             //called whenever the Login button is tapped
 *         },
 *
 *         doLogout: function() {
 *             //called whenever any Button with action=logout is tapped
 *         }
 *     });
 *
 * Here we have set up two control declarations - one for our loginButton ref and the other for any Button on the page
 * that has been given the action 'logout'. For each declaration we passed in a single event handler - in each case
 * listening for the 'tap' event, specifying the action that should be called when that Button fires the tap event.
 * Note that we specified the 'doLogin' and 'doLogout' methods as strings inside the control block - this is important.
 *
 * You can listen to as many events as you like in each control declaration, and mix and match ComponentQuery selectors
 * and refs as the keys.
 *
 * ## Routes
 *
 * As of Sencha Touch 2, Controllers can now directly specify which routes they are interested in. This enables us to
 * provide history support within our app, as well as the ability to deeply link to any part of the application that we
 * provide a route for.
 *
 * For example, let's say we have a Controller responsible for logging in and viewing user profiles, and want to make
 * those screens accessible via urls. We could achieve that like this:
 *
 *     Ext.define('MyApp.controller.Users', {
 *         extend: 'Ext.app.Controller',
 *
 *         config: {
 *             routes: {
 *                 'login': 'showLogin',
 *                 'user/:id': 'showUserById'
 *             },
 *
 *             refs: {
 *                 main: '#mainTabPanel'
 *             }
 *         },
 *
 *         //uses our 'main' ref above to add a loginpanel to our main TabPanel (note that
 *         //'loginpanel' is a custom xtype created for this application)
 *         showLogin: function() {
 *             this.getMain().add({
 *                 xtype: 'loginpanel'
 *             });
 *         },
 *
 *         //Loads the User then adds a 'userprofile' view to the main TabPanel
 *         showUserById: function(id) {
 *             MyApp.model.User.load(id, {
 *                 scope: this,
 *                 success: function(user) {
 *                     this.getMain().add({
 *                         xtype: 'userprofile',
 *                         user: user
 *                     });
 *                 }
 *             });
 *         }
 *     });
 *
 * The routes we specified above simply map the contents of the browser address bar to a Controller function to call
 * when that route is matched. The routes can be simple text like the login route, which matches against
 * http://myapp.com/#login, or contain wildcards like the 'user/:id' route, which matches urls like
 * http://myapp.com/#user/123. Whenever the address changes the Controller automatically calls the function specified.
 *
 * Note that in the showUserById function we had to first load the User instance. Whenever you use a route, the
 * function that is called by that route is completely responsible for loading its data and restoring state. This is
 * because your user could either send that url to another person or simply refresh the page, which we wipe clear any
 * cached data you had already loaded. There is a more thorough discussion of restoring state with routes in the
 * application architecture guides.
 *
 * ## Advanced Usage
 *
 * See [the Controllers guide](#!/guide/controllers) for advanced Controller usage including before filters
 * and customizing for different devices.

/**
 * @author Ed Spencer
 *
 * A Profile represents a range of devices that fall under a common category. For the vast majority of apps that use
 * device profiles, the app defines a Phone profile and a Tablet profile. Doing this enables you to easily customize
 * the experience for the different sized screens offered by those device types.
 *
 * Only one Profile can be active at a time, and each Profile defines a simple {@link #isActive} function that should
 * return either true or false. The first Profile to return true from its isActive function is set as your Application's
 * {@link Ext.app.Application#currentProfile current profile}.
 *
 * A Profile can define any number of {@link #models}, {@link #views}, {@link #controllers} and {@link #stores} which
 * will be loaded if the Profile is activated. It can also define a {@link #launch} function that will be called after
 * all of its dependencies have been loaded, just before the {@link Ext.app.Application#launch application launch}
 * function is called.
 *
 * ## Sample Usage
 *
 * First you need to tell your Application about your Profile(s):
 *
 *     Ext.application({
 *         name: 'MyApp',
 *         profiles: ['Phone', 'Tablet']
 *     });
 *
 * This will load app/profile/Phone.js and app/profile/Tablet.js. Here's how we might define the Phone profile:
 *
 *     Ext.define('MyApp.profile.Phone', {
 *         extend: 'Ext.app.Profile',
 *
 *         views: ['Main'],
 *
 *         isActive: function() {
 *             return Ext.os.is.Phone;
 *         }
 *     });
 *
 * The isActive function returns true if we detect that we are running on a phone device. If that is the case the
 * Application will set this Profile active and load the 'Main' view specified in the Profile's {@link #views} config.
 *
 * ## Class Specializations
 *
 * Because Profiles are specializations of an application, all of the models, views, controllers and stores defined
 * in a Profile are expected to be namespaced under the name of the Profile. Here's an expanded form of the example
 * above:
 *
 *     Ext.define('MyApp.profile.Phone', {
 *         extend: 'Ext.app.Profile',
 *
 *         views: ['Main'],
 *         controllers: ['Signup'],
 *         models: ['MyApp.model.Group'],
 *
 *         isActive: function() {
 *             return Ext.os.is.Phone;
 *         }
 *     });
 *
 * In this case, the Profile is going to load *app/view/phone/Main.js*, *app/controller/phone/Signup.js* and
 * *app/model/Group.js*. Notice that in each of the first two cases the name of the profile ('phone' in this case) was
 * injected into the class names. In the third case we specified the full Model name (for Group) so the Profile name
 * was not injected.
 *
 * For a fuller understanding of the ideas behind Profiles and how best to use them in your app, we suggest you read
 * the [device profiles guide](#!/guide/profiles).

 * @author Ed Spencer

 *
 * Ext.app.Application defines the set of {@link Ext.data.Model Models}, {@link Ext.app.Controller Controllers},
 * {@link Ext.app.Profile Profiles}, {@link Ext.data.Store Stores} and {@link Ext.Component Views} that an application
 * consists of. It automatically loads all of those dependencies and can optionally specify a {@link #launch} function
 * that will be called when everything is ready.
 *
 * Sample usage:
 *
 *     Ext.application({
 *         name: 'MyApp',
 *
 *         models: ['User', 'Group'],
 *         stores: ['Users'],
 *         controllers: ['Users'],
 *         views: ['Main', 'ShowUser'],
 *
 *         launch: function() {
 *             Ext.create('MyApp.view.Main');
 *         }
 *     });
 *
 * Creating an Application instance is the only time in Sencha Touch 2 that we don't use Ext.create to create the new
 * instance. Instead, the {@link Ext#application} function instantiates an Ext.app.Application internally,
 * automatically loading the Ext.app.Application class if it is not present on the page already and hooking in to
 * {@link Ext#onReady} before creating the instance itself. An alternative is to use Ext.create inside an Ext.onReady
 * callback, but Ext.application is preferred.
 *
 * ## Dependencies
 *
 * Application follows a simple convention when it comes to specifying the controllers, views, models, stores and
 * profiles it requires. By default it expects each of them to be found inside the *app/controller*, *app/view*,
 * *app/model*, *app/store* and *app/profile* directories in your app - if you follow this convention you can just
 * specify the last part of each class name and Application will figure out the rest for you:
 *
 *     Ext.application({
 *         name: 'MyApp',
 *
 *         controllers: ['Users'],
 *         models: ['User', 'Group'],
 *         stores: ['Users'],
 *         views: ['Main', 'ShowUser']
 *     });
 *
 * The example above will load 6 files:
 *
 * - app/model/User.js
 * - app/model/Group.js
 * - app/store/Users.js
 * - app/controller/Users.js
 * - app/view/Main.js
 * - app/view/ShowUser.js
 *
 * ### Nested Dependencies
 *
 * For larger apps it's common to split the models, views and controllers into subfolders so keep the project
 * organized. This is especially true of views - it's not unheard of for large apps to have over a hundred separate
 * view classes so organizing them into folders can make maintenance much simpler.
 *
 * To specify dependencies in subfolders just use a period (".") to specify the folder:
 *
 *     Ext.application({
 *         name: 'MyApp',
 *
 *         controllers: ['Users', 'nested.MyController'],
 *         views: ['products.Show', 'products.Edit', 'user.Login']
 *     });
 *
 * In this case these 5 files will be loaded:
 *
 * - app/controller/Users.js
 * - app/controller/nested/MyController.js
 * - app/view/products/Show.js
 * - app/view/products/Edit.js
 * - app/view/user/Login.js
 *
 * Note that we can mix and match within each configuration here - for each model, view, controller, profile or store
 * you can specify either just the final part of the class name (if you follow the directory conventions), or the full
 * class name.
 *
 * ### External Dependencies
 *
 * Finally, we can specify application dependencies from outside our application by fully-qualifying the classes we
 * want to load. A common use case for this is sharing authentication logic between multiple applications. Perhaps you
 * have several apps that login via a common user database and you want to share that code between them. An easy way to
 * do this is to create a folder alongside your app folder and then add its contents as dependencies for your app.
 *
 * For example, let's say our shared login code contains a login controller, a user model and a login form view. We
 * want to use all of these in our application:
 *
 *     Ext.Loader.setPath({
 *         'Auth': 'Auth'
 *     });
 *
 *     Ext.application({
 *         views: ['Auth.view.LoginForm', 'Welcome'],
 *         controllers: ['Auth.controller.Sessions', 'Main'],
 *         models: ['Auth.model.User']
 *     });
 *
 * This will load the following files:
 *
 * - Auth/view/LoginForm.js
 * - Auth/controller/Sessions.js
 * - Auth/model/User.js
 * - app/view/Welcome.js
 * - app/controller/Main.js
 *
 * The first three were loaded from outside our application, the last two from the application itself. Note how we can
 * still mix and match application files and external dependency files.
 *
 * Note that to enable the loading of external dependencies we just have to tell the Loader where to find those files,
 * which is what we do with the Ext.Loader.setPath call above. In this case we're telling the Loader to find any class
 * starting with the 'Auth' namespace inside our 'Auth' folder. This means we can drop our common Auth code into our
 * application alongside the app folder and the framework will be able to figure out how to load everything.
 *
 * ## Launching
 *
 * Each Application can define a {@link Ext.app.Application#launch launch} function, which is called as soon as all of
 * your app's classes have been loaded and the app is ready to be launched. This is usually the best place to put any
 * application startup logic, typically creating the main view structure for your app.
 *
 * In addition to the Application launch function, there are two other places you can put app startup logic. Firstly,
 * each Controller is able to define an {@link Ext.app.Controller#init init} function, which is called before the
 * Application launch function. Secondly, if you are using Device Profiles, each Profile can define a
 * {@link Ext.app.Profile#launch launch} function, which is called after the Controller init functions but before the
 * Application launch function.
 *
 * Note that only the active Profile has its launch function called - for example if you define profiles for Phone and
 * Tablet and then launch the app on a tablet, only the Tablet Profile's launch function is called.
 *
 * 1. Controller#init functions called
 * 2. Profile#launch function called
 * 3. Application#launch function called
 * 4. Controller#launch functions called
 *
 * When using Profiles it is common to place most of the bootup logic inside the Profile launch function because each
 * Profile has a different set of views that need to be constructed at startup.
 *
 * ## Adding to Home Screen
 *
 * iOS devices allow your users to add your app to their home screen for easy access. iOS allows you to customize
 * several aspects of this, including the icon that will appear on the home screen and the startup image. These can be
 * specified in the Ext.application setup block:
 *
 *     Ext.application({
 *         name: 'MyApp',
 *
 *         {@link #icon}: 'resources/img/icon.png',
 *         {@link #isIconPrecomposed}: false,
 *         {@link #startupImage}: {
 *             '320x460': 'resources/startup/320x460.jpg',
 *             '640x920': 'resources/startup/640x920.png',
 *             '640x1096': 'resources/startup/640x1096.png',
 *             '768x1004': 'resources/startup/768x1004.png',
 *             '748x1024': 'resources/startup/748x1024.png',
 *             '1536x2008': 'resources/startup/1536x2008.png',
 *             '1496x2048': 'resources/startup/1496x2048.png'
 *         }
 *     });
 *
 * When the user adds your app to the home screen, your resources/img/icon.png file will be used as the application
 * {@link #icon}. We also used the {@link #isIconPrecomposed} configuration to turn off the gloss effect that is automatically added
 * to icons in iOS. Finally we used the {@link #startupImage} configuration to provide the images that will be displayed 
 * while your application is starting up. See also {@link #statusBarStyle}.

 * [intro to applications guide](#!/guide/apps_intro), which lays out the core principles of writing apps

 * @class Ext.carousel.Carousel
 * @author Jacky Nguyen <jacky@sencha.com>
 *
 * Carousels, like [tabs](#!/guide/tabs), are a great way to allow the user to swipe through multiple full-screen pages.
 * A Carousel shows only one of its pages at a time but allows you to swipe through with your finger.
 *
 * Carousels can be oriented either horizontally or vertically and are easy to configure - they just work like any other
 * Container. Here's how to set up a simple horizontal Carousel:
 *
 *     @example
 *     Ext.create('Ext.Carousel', {
 *         fullscreen: true,
 *
 *         defaults: {
 *             styleHtmlContent: true
 *         },
 *
 *         items: [
 *             {
 *                 html : 'Item 1',
 *                 style: 'background-color: #5E99CC'
 *             },
 *             {
 *                 html : 'Item 2',
 *                 style: 'background-color: #759E60'
 *             },
 *             {
 *                 html : 'Item 3'
 *             }
 *         ]
 *     });
 *
 * We can also make Carousels orient themselves vertically:
 *
 *     @example preview
 *     Ext.create('Ext.Carousel', {
 *         fullscreen: true,
 *         direction: 'vertical',
 *
 *         defaults: {
 *             styleHtmlContent: true
 *         },
 *
 *         items: [
 *             {
 *                 html : 'Item 1',
 *                 style: 'background-color: #759E60'
 *             },
 *             {
 *                 html : 'Item 2',
 *                 style: 'background-color: #5E99CC'
 *             }
 *         ]
 *     });
 *
 * ### Common Configurations
 * * {@link #ui} defines the style of the carousel
 * * {@link #direction} defines the direction of the carousel
 * * {@link #indicator} defines if the indicator show be shown
 *
 * ### Useful Methods
 * * {@link #next} moves to the next card
 * * {@link #previous} moves to the previous card
 * * {@link #setActiveItem} moves to the passed card
 *
 * ## Further Reading
 *
 * For more information about Carousels see the [Carousel guide](#!/guide/carousel).

/**
 * @aside guide dataview
 *
 * DataView makes it easy to create lots of components dynamically, usually based off a {@link Ext.data.Store Store}.
 * It's great for rendering lots of data from your server backend or any other data source and is what powers
 * components like {@link Ext.List}.
 *
 * Use DataView whenever you want to show sets of the same component many times, for examples in apps like these:
 *
 * - List of messages in an email app
 * - Showing latest news/tweets
 * - Tiled set of albums in an HTML5 music player
 *
 * # Creating a Simple DataView
 *
 * At its simplest, a DataView is just a Store full of data and a simple template that we use to render each item:
 *
 *     @example miniphone preview
 *     var touchTeam = Ext.create('Ext.DataView', {
 *         fullscreen: true,
 *         store: {
 *             fields: ['name', 'age'],
 *             data: [
 *                 {name: 'Jamie',  age: 100},
 *                 {name: 'Rob',   age: 21},
 *                 {name: 'Tommy', age: 24},
 *                 {name: 'Jacky', age: 24},
 *                 {name: 'Ed',   age: 26}
 *             ]
 *         },
 *
 *         itemTpl: '<div>{name} is {age} years old</div>'
 *     });
 *
 * Here we just defined everything inline so it's all local with nothing being loaded from a server. For each of the 5
 * data items defined in our Store, DataView will render a {@link Ext.Component Component} and pass in the name and age
 * data. The component will use the tpl we provided above, rendering the data in the curly bracket placeholders we
 * provided.
 *
 * Because DataView is integrated with Store, any changes to the Store are immediately reflected on the screen. For
 * example, if we add a new record to the Store it will be rendered into our DataView:
 *
 *     touchTeam.getStore().add({
 *         name: 'Abe Elias',
 *         age: 33
 *     });
 *
 * We didn't have to manually update the DataView, it's just automatically updated. The same happens if we modify one
 * of the existing records in the Store:
 *
 *     touchTeam.getStore().getAt(0).set('age', 42);
 *
 * This will get the first record in the Store (Jamie), change the age to 42 and automatically update what's on the
 * screen.
 *
 *     @example miniphone
 *     var touchTeam = Ext.create('Ext.DataView', {
 *         fullscreen: true,
 *         store: {
 *             fields: ['name', 'age'],
 *             data: [
 *                 {name: 'Jamie',  age: 100},
 *                 {name: 'Rob',   age: 21},
 *                 {name: 'Tommy', age: 24},
 *                 {name: 'Jacky', age: 24},
 *                 {name: 'Ed',   age: 26}
 *             ]
 *         },

 * # Loading data from a server
 *
 * We often want to load data from our server or some other web service so that we don't have to hard code it all
 * locally. Let's say we want to load all of the latest tweets about Sencha Touch into a DataView, and for each one
 * render the user's profile picture, user name and tweet message. To do this all we have to do is modify the
 * {@link #store} and {@link #itemTpl} a little:
 *
 *     @example portrait
 *     Ext.create('Ext.DataView', {
 *         fullscreen: true,
 *         cls: 'twitterView',
 *         store: {
 *             autoLoad: true,
 *             fields: ['from_user', 'text', 'profile_image_url'],
 *
 *             proxy: {
 *                 type: 'jsonp',
 *                 url: 'http://search.twitter.com/search.json?q=Sencha Touch',
 *
 *                 reader: {
 *                     type: 'json',
 *                     rootProperty: 'results'
 *                 }
 *             }
 *         },
 *
 *         itemTpl: '<img src="{profile_image_url}" /><h2>{from_user}</h2><p>{text}</p><div style="clear: both"></div>'
 *     });
 *
 * The Store no longer has hard coded data, instead we've provided a {@link Ext.data.proxy.Proxy Proxy}, which fetches
 * the data for us. In this case we used a JSON-P proxy so that we can load from Twitter's JSON-P search API. We also
 * specified the fields present for each tweet, and used Store's {@link Ext.data.Store#autoLoad autoLoad} configuration
 * to load automatically. Finally, we configured a Reader to decode the response from Twitter, telling it to expect
 * JSON and that the tweets can be found in the 'results' part of the JSON response.
 *
 * The last thing we did is update our template to render the image, Twitter username and message. All we need to do
 * now is add a little CSS to style the list the way we want it and we end up with a very basic Twitter viewer. Click
 * the preview button on the example above to see it in action.

/**
 * @author Ed Spencer
 *
 * Readers are used to interpret data to be loaded into a {@link Ext.data.Model Model} instance or a {@link
 * Ext.data.Store Store} - often in response to an AJAX request. In general there is usually no need to create
 * a Reader instance directly, since a Reader is almost always used together with a {@link Ext.data.proxy.Proxy Proxy},
 * and is configured using the Proxy's {@link Ext.data.proxy.Proxy#cfg-reader reader} configuration property:
 *
 *     Ext.define("User", {
 *         extend: "Ext.data.Model",
 *         config: {
 *             fields: [
 *                 "id",
 *                 "name"
 *             ]
 *         }
 *     });
 *
 *     Ext.create("Ext.data.Store", {
 *         model: "User",
 *         autoLoad: true,
 *         storeId: "usersStore",
 *         proxy: {
 *             type: "ajax",
 *             url : "users.json",
 *             reader: {
 *                 type: "json",
 *                 rootProperty: "users"
 *             }
 *         }
 *     });
 *
 *     Ext.create("Ext.List", {
 *         fullscreen: true,
 *         itemTpl: "{name} (id: '{id}')",
 *         store: "usersStore"
 *     });
 *
 * The above reader is configured to consume a JSON string that looks something like this:
 *
 *     {
 *         "success": true,
 *         "users": [
 *             { "name": "User 1" },
 *             { "name": "User 2" }
 *         ]
 *     }
 *
 *
 * # Loading Nested Data
 *
 * Readers have the ability to automatically load deeply-nested data objects based on the {@link Ext.data.association.Association
 * associations} configured on each Model. Below is an example demonstrating the flexibility of these associations in a
 * fictional CRM system which manages a User, their Orders, OrderItems and Products. First we'll define the models:
 *
 *     Ext.define("User", {
 *         extend: "Ext.data.Model",
 *         config: {
 *             fields: [
 *                 "id",
 *                 "name"
 *             ],
 *             hasMany: {
 *                 model: "Order",
 *                 name: "orders"
 *             },
 *             proxy: {
 *                 type: "rest",
 *                 url : "users.json",
 *                 reader: {
 *                     type: "json",
 *                     rootProperty: "users"
 *                 }
 *             }
 *         }
 *     });
 *
 *     Ext.define("Order", {
 *         extend: "Ext.data.Model",
 *         config: {
 *             fields: [
 *                 "id", "total"
 *             ],
 *             hasMany: {
 *                 model: "OrderItem",
 *                 name: "orderItems",
 *                 associationKey: "order_items"
 *             },
 *             belongsTo: "User"
 *         }
 *     });
 *
 *     Ext.define("OrderItem", {
 *         extend: "Ext.data.Model",
 *         config: {
 *             fields: [
 *                 "id",
 *                 "price",
 *                 "quantity",
 *                 "order_id",
 *                 "product_id"
 *             ],
 *             belongsTo: [
 *                 "Order", {
 *                     model: "Product",
 *                     associationKey: "product"
 *                 }
 *             ]
 *         }
 *     });
 *
 *     Ext.define("Product", {
 *         extend: "Ext.data.Model",
 *         config: {
 *             fields: [
 *                 "id",
 *                 "name"
 *             ]
 *         },
 *         hasMany: "OrderItem"
 *     });
 *
 *     var store = Ext.create('Ext.data.Store', {
 *         model: "User"
 *     });
 *
 *     store.load({
 *         callback: function() {
 *             var output = [];
 *
 *             // the user that was loaded
 *             var user = store.first();
 *
 *             output.push("Orders for " + user.get('name') + ":");
 *
 *             // iterate over the Orders for each User
 *             user.orders().each(function(order) {
 *                 output.push("Order ID: " + order.get('id') + ", which contains items:");
 *
 *                 // iterate over the OrderItems for each Order
 *                 order.orderItems().each(function(orderItem) {
 *                     // We know that the Product data is already loaded, so we can use the
 *                     // synchronous getProduct() method. Usually, we would use the 
 *                     // asynchronous version (see Ext.data.association.BelongsTo).
 *                     var product = orderItem.getProduct();
 *                     output.push(orderItem.get("quantity") + " orders of " + product.get("name"));
 *                 });
 *             });
 *             Ext.Msg.alert('Output:', output.join("<br/>"));
 *         }
 *     });
 *
 * This may be a lot to take in - basically a User has many Orders, each of which is composed of several OrderItems.
 * Finally, each OrderItem has a single Product. This allows us to consume data like this (_users.json_):
 *
 *     {
 *         "users": [
 *             {
 *                 "id": 123,
 *                 "name": "Ed",
 *                 "orders": [
 *                     {
 *                         "id": 50,
 *                         "total": 100,
 *                         "order_items": [
 *                             {
 *                                 "id"      : 20,
 *                                 "price"   : 40,
 *                                 "quantity": 2,
 *                                 "product" : {
 *                                     "id": 1000,
 *                                     "name": "MacBook Pro"
 *                                 }
 *                             },
 *                             {
 *                                 "id"      : 21,
 *                                 "price"   : 20,
 *                                 "quantity": 3,
 *                                 "product" : {
 *                                     "id": 1001,
 *                                     "name": "iPhone"
 *                                 }

 *     }
 *
 * The JSON response is deeply nested - it returns all Users (in this case just 1 for simplicity's sake), all of the
 * Orders for each User (again just 1 in this case), all of the OrderItems for each Order (2 order items in this case),
 * and finally the Product associated with each OrderItem.
 *
 * Running the code above results in the following:
 *
 *     Orders for Ed:
 *     Order ID: 50, which contains items:
 *     2 orders of MacBook Pro
 *     3 orders of iPhone

/**
 * The JSON Reader is used by a Proxy to read a server response that is sent back in JSON format. This usually happens
 * as a result of loading a Store - for example we might create something like this:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['id', 'name', 'email']
 *         }
 *     });
 *
 *     var store = Ext.create('Ext.data.Store', {
 *         model: 'User',
 *         proxy: {
 *             type: 'ajax',
 *             url : 'users.json',
 *             reader: {
 *                 type: 'json'
 *             }
 *         }
 *     });
 *
 * The example above creates a 'User' model. Models are explained in the {@link Ext.data.Model Model} docs if you're not
 * already familiar with them.
 *
 * We created the simplest type of JSON Reader possible by simply telling our {@link Ext.data.Store Store}'s {@link
 * Ext.data.proxy.Proxy Proxy} that we want a JSON Reader. The Store automatically passes the configured model to the
 * Store, so it is as if we passed this instead:
 *
 *     reader: {
 *         type : 'json',
 *         model: 'User'
 *     }
 *
 * The reader we set up is ready to read data from our server - at the moment it will accept a response like this:
 *
 *     [
 *         {
 *             "id": 1,
 *             "name": "Ed Spencer",
 *             "email": "ed@sencha.com"
 *         },
 *         {
 *             "id": 2,
 *             "name": "Abe Elias",
 *             "email": "abe@sencha.com"
 *         }
 *     ]
 *
 * ## Reading other JSON formats
 *
 * If you already have your JSON format defined and it doesn't look quite like what we have above, you can usually pass
 * JsonReader a couple of configuration options to make it parse your format. For example, we can use the
 * {@link #rootProperty} configuration to parse data that comes back like this:
 *
 *     {
 *         "users": [
 *            {
 *                "id": 1,
 *                "name": "Ed Spencer",
 *                "email": "ed@sencha.com"
 *            },
 *            {
 *                "id": 2,
 *                "name": "Abe Elias",
 *                "email": "abe@sencha.com"
 *            }
 *         ]
 *     }
 *
 * To parse this we just pass in a {@link #rootProperty} configuration that matches the 'users' above:
 *
 *     reader: {
 *         type: 'json',
 *         rootProperty: 'users'
 *     }
 *
 * Sometimes the JSON structure is even more complicated. Document databases like CouchDB often provide metadata around
 * each record inside a nested structure like this:
 *
 *     {
 *         "total": 122,
 *         "offset": 0,
 *         "users": [
 *             {
 *                 "id": "ed-spencer-1",
 *                 "value": 1,
 *                 "user": {
 *                     "id": 1,
 *                     "name": "Ed Spencer",
 *                     "email": "ed@sencha.com"
 *                 }
 *             }
 *         ]
 *     }
 *
 * In the case above the record data is nested an additional level inside the "users" array as each "user" item has
 * additional metadata surrounding it ('id' and 'value' in this case). To parse data out of each "user" item in the JSON
 * above we need to specify the {@link #record} configuration like this:
 *
 *     reader: {
 *         type: 'json',
 *         record: 'user',
 *         rootProperty: 'users'
 *     }
 *
 * ## Response MetaData
 *
 * The server can return metadata in its response, in addition to the record data, that describe attributes
 * of the data set itself or are used to reconfigure the Reader. To pass metadata in the response you simply
 * add a `metaData` attribute to the root of the response data. The metaData attribute can contain anything,
 * but supports a specific set of properties that are handled by the Reader if they are present:
 *
 * - {@link #idProperty}: property name for the primary key field of the data
 * - {@link #rootProperty}: the property name of the root response node containing the record data
 * - {@link #totalProperty}: property name for the total number of records in the data
 * - {@link #successProperty}: property name for the success status of the response
 * - {@link #messageProperty}: property name for an optional response message
 * - {@link Ext.data.Model#cfg-fields fields}: Config used to reconfigure the Model's fields before converting the
 *   response data into records
 *
 * An initial Reader configuration containing all of these properties might look like this ("fields" would be
 * included in the Model definition, not shown):
 *
 *     reader: {
 *         type: 'json',
 *         idProperty: 'id',
 *         rootProperty: 'root',
 *         totalProperty: 'total',
 *         successProperty: 'success',
 *         messageProperty: 'message'
 *     }
 *
 * If you were to pass a response object containing attributes different from those initially defined above, you could
 * use the `metaData` attribute to reconfigure the Reader on the fly. For example:
 *
 *     {
 *         "count": 1,
 *         "ok": true,
 *         "msg": "Users found",
 *         "users": [{
 *             "userId": 123,
 *             "name": "Ed Spencer",
 *             "email": "ed@sencha.com"
 *         }],
 *         "metaData": {
 *             "idProperty": 'userId',
 *             "rootProperty": "users",
 *             "totalProperty": 'count',
 *             "successProperty": 'ok',
 *             "messageProperty": 'msg'
 *         }
 *     }
 *
 * You can also place any other arbitrary data you need into the `metaData` attribute which will be ignored by the Reader,
 * but will be accessible via the Reader's {@link #metaData} property. Application code can then process the passed
 * metadata in any way it chooses.
 *
 * A simple example for how this can be used would be customizing the fields for a Model that is bound to a grid. By passing
 * the `fields` property the Model will be automatically updated by the Reader internally, but that change will not be
 * reflected automatically in the grid unless you also update the column configuration. You could do this manually, or you
 * could simply pass a standard grid column config object as part of the `metaData` attribute
 * and then pass that along to the grid. Here's a very simple example for how that could be accomplished:
 *
 *     // response format:
 *     {
 *         ...
 *         "metaData": {
 *             "fields": [
 *                 { "name": "userId", "type": "int" },
 *                 { "name": "name", "type": "string" },
 *                 { "name": "birthday", "type": "date", "dateFormat": "Y-j-m" },
 *             ],
 *             "columns": [
 *                 { "text": "User ID", "dataIndex": "userId", "width": 40 },
 *                 { "text": "User Name", "dataIndex": "name", "flex": 1 },
 *                 { "text": "Birthday", "dataIndex": "birthday", "flex": 1, "format": 'Y-j-m', "xtype": "datecolumn" }
 *             ]
 *         }
 *     }

/**
 * @author Ed Spencer
 * @aside guide proxies
 *
 * Proxies are used by {@link Ext.data.Store Stores} to handle the loading and saving of {@link Ext.data.Model Model}
 * data. Usually developers will not need to create or interact with proxies directly.
 *
 * # Types of Proxy
 *
 * There are two main types of Proxy - {@link Ext.data.proxy.Client Client} and {@link Ext.data.proxy.Server Server}.
 * The Client proxies save their data locally and include the following subclasses:
 *
 * - {@link Ext.data.proxy.LocalStorage LocalStorageProxy} - saves its data to localStorage if the browser supports it
 * - {@link Ext.data.proxy.Memory MemoryProxy} - holds data in memory only, any data is lost when the page is refreshed
 *
 * The Server proxies save their data by sending requests to some remote server. These proxies include:
 *
 * - {@link Ext.data.proxy.Ajax Ajax} - sends requests to a server on the same domain
 * - {@link Ext.data.proxy.JsonP JsonP} - uses JSON-P to send requests to a server on a different domain
 *
 * Proxies operate on the principle that all operations performed are either Create, Read, Update or Delete. These four
 * operations are mapped to the methods {@link #create}, {@link #read}, {@link #update} and {@link #destroy}
 * respectively. Each Proxy subclass implements these functions.
 *
 * The CRUD methods each expect an {@link Ext.data.Operation Operation} object as the sole argument. The Operation
 * encapsulates information about the action the Store wishes to perform, the {@link Ext.data.Model model} instances
 * that are to be modified, etc. See the {@link Ext.data.Operation Operation} documentation for more details. Each CRUD
 * method also accepts a callback function to be called asynchronously on completion.
 *
 * Proxies also support batching of Operations via a {@link Ext.data.Batch batch} object, invoked by the {@link #batch}
 * method.

/**
 * @class Ext.data.Types
 *
 * This is a static class containing the system-supplied data types which may be given to a {@link Ext.data.Field Field}.
 *
 * The properties in this class are used as type indicators in the {@link Ext.data.Field Field} class, so to
 * test whether a Field is of a certain type, compare the {@link Ext.data.Field#type type} property against properties
 * of this class.
 *
 * Developers may add their own application-specific data types to this class. Definition names must be UPPERCASE.
 * each type definition must contain three properties:
 *
 * - `convert`: {Function} - A function to convert raw data values from a data block into the data
 * to be stored in the Field. The function is passed the following parameters:
 *   + `v`: {Mixed} - The data value as read by the Reader, if `undefined` will use
 * the configured `{@link Ext.data.Field#defaultValue defaultValue}`.
 *   + `rec`: {Mixed} - The data object containing the row as read by the Reader.
 * Depending on the Reader type, this could be an Array ({@link Ext.data.reader.Array ArrayReader}), an object
 * ({@link Ext.data.reader.Json JsonReader}), or an XML element.
 * - `sortType`: {Function} - A function to convert the stored data into comparable form, as defined by {@link Ext.data.SortTypes}.
 * - `type`: {String} - A textual data type name.
 *
 * For example, to create a VELatLong field (See the Microsoft Bing Mapping API) containing the latitude/longitude value of a datapoint on a map from a JsonReader data block
 * which contained the properties `lat` and `long`, you would define a new data type like this:
 *
 *     // Add a new Field data type which stores a VELatLong object in the Record.
 *     Ext.data.Types.VELATLONG = {
 *         convert: function(v, data) {
 *             return new VELatLong(data.lat, data.long);
 *         },
 *         sortType: function(v) {
 *             return v.Latitude;  // When sorting, order by latitude

/**
 * @author Ed Spencer
 * @aside guide models
 *
 * Fields are used to define what a Model is. They aren't instantiated directly - instead, when we create a class that
 * extends {@link Ext.data.Model}, it will automatically create a Field instance for each field configured in a {@link
 * Ext.data.Model Model}. For example, we might set up a model like this:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 'name', 'email',
 *                 {name: 'age', type: 'int'},
 *                 {name: 'gender', type: 'string', defaultValue: 'Unknown'}
 *             ]
 *         }
 *     });
 *
 * Four fields will have been created for the User Model - name, email, age, and gender. Note that we specified a couple
 * of different formats here; if we only pass in the string name of the field (as with name and email), the field is set
 * up with the 'auto' type. It's as if we'd done this instead:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 {name: 'name', type: 'auto'},
 *                 {name: 'email', type: 'auto'},
 *                 {name: 'age', type: 'int'},
 *                 {name: 'gender', type: 'string', defaultValue: 'Unknown'}
 *             ]
 *         }
 *     });
 *
 * # Types and conversion
 *
 * The {@link #type} is important - it's used to automatically convert data passed to the field into the correct format.
 * In our example above, the name and email fields used the 'auto' type and will just accept anything that is passed
 * into them. The 'age' field had an 'int' type however, so if we passed 25.4 this would be rounded to 25.
 *
 * Sometimes a simple type isn't enough, or we want to perform some processing when we load a Field's data. We can do
 * this using a {@link #convert} function. Here, we're going to create a new field based on another:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 'name', 'email',
 *                 {name: 'age', type: 'int'},
 *                 {name: 'gender', type: 'string', defaultValue: 'Unknown'},
 *
 *                 {
 *                     name: 'firstName',
 *                     convert: function(value, record) {
 *                         var fullName  = record.get('name'),
 *                             splits    = fullName.split(" "),
 *                             firstName = splits[0];
 *
 *                         return firstName;
 *                     }
 *                 }
 *             ]
 *         }
 *     });
 *
 * Now when we create a new User, the firstName is populated automatically based on the name:
 *
 *     var ed = Ext.create('User', {name: 'Ed Spencer'});
 *
 *     console.log(ed.get('firstName')); //logs 'Ed', based on our convert function
 *
 * In fact, if we log out all of the data inside ed, we'll see this:
 *
 *     console.log(ed.data);
 *
 *     //outputs this:
 *     {
 *         age: 0,
 *         email: "",
 *         firstName: "Ed",
 *         gender: "Unknown",
 *         name: "Ed Spencer"
 *     }
 *
 * The age field has been given a default of zero because we made it an int type. As an auto field, email has defaulted
 * to an empty string. When we registered the User model we set gender's {@link #defaultValue} to 'Unknown' so we see
 * that now. Let's correct that and satisfy ourselves that the types work as we expect:
 *
 *     ed.set('gender', 'Male');
 *     ed.get('gender'); //returns 'Male'
 *
 *     ed.set('age', 25.4);
 *     ed.get('age'); //returns 25 - we wanted an int, not a float, so no decimal places allowed

 * The ModelManager keeps track of all {@link Ext.data.Model} types defined in your application.
 * 
 * ## Creating Model Instances
 * 
 * Model instances can be created by using the {@link Ext.ClassManager#create Ext.create} method. Ext.create replaces
 * the deprecated {@link #create Ext.ModelManager.create} method. It is also possible to create a model instance
 * this by using the Model type directly. The following 3 snippets are equivalent:
 * 
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['first', 'last']
 *         }
 *     });
 * 
 *     // method 1, create using Ext.create (recommended)
 *     Ext.create('User', {
 *         first: 'Ed',
 *         last: 'Spencer'
 *     });
 * 
 *     // method 2, create on the type directly
 *     new User({
 *         first: 'Ed',
 *         last: 'Spencer'
 *     });
 * 
 *     // method 3, create through the manager (deprecated)
 *     Ext.ModelManager.create({
 *         first: 'Ed',
 *         last: 'Spencer'
 *     }, 'User');
 *
 * ## Accessing Model Types
 * 
 * A reference to a Model type can be obtained by using the {@link #getModel} function. Since models types
 * are normal classes, you can access the type directly. The following snippets are equivalent:
 * 
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['first', 'last']
 *         }
 *     });
 * 
 *     // method 1, access model type through the manager
 *     var UserType = Ext.ModelManager.getModel('User');
 * 
 *     // method 2, reference the type directly
 *     var UserType = User;

/**
 * @author Ed Spencer
 * @aside guide proxies
 *
 * AjaxProxy is one of the most widely-used ways of getting data into your application. It uses AJAX
 * requests to load data from the server, usually to be placed into a {@link Ext.data.Store Store}.
 * Let's take a look at a typical setup. Here we're going to set up a Store that has an AjaxProxy.
 * To prepare, we'll also set up a {@link Ext.data.Model Model}:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['id', 'name', 'email']
 *         }
 *     });
 *
 *     // The Store contains the AjaxProxy as an inline configuration
 *     var store = Ext.create('Ext.data.Store', {
 *         model: 'User',
 *         proxy: {
 *             type: 'ajax',
 *             url : 'users.json'
 *         }
 *     });
 *
 *     store.load();
 *
 * Our example is going to load user data into a Store, so we start off by defining a
 * {@link Ext.data.Model Model} with the fields that we expect the server to return. Next we set up
 * the Store itself, along with a {@link Ext.data.Store#proxy proxy} configuration. This
 * configuration was automatically turned into an Ext.data.proxy.Ajax instance, with the url we
 * specified being passed into AjaxProxy's constructor. It's as if we'd done this:
 *
 *     Ext.create('Ext.data.proxy.Ajax', {
 *         config: {
 *             url: 'users.json',
 *             model: 'User',
 *             reader: 'json'
 *         }
 *     });
 *
 * A couple of extra configurations appeared here - {@link #model} and {@link #reader}. These are
 * set by default when we create the proxy via the Store - the Store already knows about the Model,
 * and Proxy's default {@link Ext.data.reader.Reader Reader} is {@link Ext.data.reader.Json JsonReader}.
 *
 * Now when we call store.load(), the AjaxProxy springs into action, making a request to the url we
 * configured ('users.json' in this case). As we're performing a read, it sends a GET request to
 * that url (see {@link #actionMethods} to customize this - by default any kind of read will be sent
 * as a GET request and any kind of write will be sent as a POST request).
 *
 * ## Limitations
 *
 * AjaxProxy cannot be used to retrieve data from other domains. If your application is running on
 * http://domainA.com it cannot load data from http://domainB.com because browsers have a built-in
 * security policy that prohibits domains talking to each other via AJAX.
 *
 * If you need to read data from another domain and can't set up a proxy server (some software that
 * runs on your own domain's web server and transparently forwards requests to http://domainB.com,
 * making it look like they actually came from http://domainA.com), you can use
 * {@link Ext.data.proxy.JsonP} and a technique known as JSON-P (JSON with Padding), which can help
 * you get around the problem so long as the server on http://domainB.com is set up to support
 * JSON-P responses. See {@link Ext.data.proxy.JsonP JsonPProxy}'s introduction docs for more details.
 *
 * ## Readers and Writers
 *
 * AjaxProxy can be configured to use any type of {@link Ext.data.reader.Reader Reader} to decode
 * the server's response. If no Reader is supplied, AjaxProxy will default to using a
 * {@link Ext.data.reader.Json JsonReader}. Reader configuration can be passed in as a simple
 * object, which the Proxy automatically turns into a {@link Ext.data.reader.Reader Reader} instance:
 *
 *     var proxy = Ext.create('Ext.data.proxy.Ajax', {
 *         config: {
 *             model: 'User',
 *             reader: {
 *                 type: 'xml',
 *                 root: 'users'
 *             }
 *         }
 *     });
 *
 *     proxy.getReader(); //returns an {@link Ext.data.reader.Xml XmlReader} instance based on the config we supplied
 *
 * ## Url generation
 *
 * AjaxProxy automatically inserts any sorting, filtering, paging and grouping options into the url
 * it generates for each request. These are controlled with the following configuration options:
 *
 * - {@link #pageParam} - controls how the page number is sent to the server (see also
 *   {@link #startParam} and {@link #limitParam})
 * - {@link #sortParam} - controls how sort information is sent to the server
 * - {@link #groupParam} - controls how grouping information is sent to the server
 * - {@link #filterParam} - controls how filter information is sent to the server
 *
 * Each request sent by AjaxProxy is described by an {@link Ext.data.Operation Operation}. To see
 * how we can customize the generated urls, let's say we're loading the Proxy with the following
 * Operation:
 *
 *     var operation = Ext.create('Ext.data.Operation', {
 *         action: 'read',
 *         page  : 2
 *     });
 *
 * Now we'll issue the request for this Operation by calling {@link #read}:
 *
 *     var proxy = Ext.create('Ext.data.proxy.Ajax', {
 *         url: '/users'
 *     });
 *
 *     proxy.read(operation); // GET /users?page=2
 *
 * Easy enough - the Proxy just copied the page property from the Operation. We can customize how
 * this page data is sent to the server:
 *
 *     var proxy = Ext.create('Ext.data.proxy.Ajax', {
 *         url: '/users',
 *         pageParam: 'pageNumber'
 *     });
 *
 *     proxy.read(operation); // GET /users?pageNumber=2
 *
 * Alternatively, our Operation could have been configured to send start and limit parameters
 * instead of page:
 *
 *     var operation = Ext.create('Ext.data.Operation', {
 *         action: 'read',
 *         start : 50,
 *         limit : 25
 *     });
 *
 *     var proxy = Ext.create('Ext.data.proxy.Ajax', {
 *         url: '/users'
 *     });
 *
 *     proxy.read(operation); // GET /users?start=50&limit;=25
 *
 * Again we can customize this url:
 *
 *     var proxy = Ext.create('Ext.data.proxy.Ajax', {
 *         url: '/users',
 *         startParam: 'startIndex',
 *         limitParam: 'limitIndex'
 *     });
 *
 *     proxy.read(operation); // GET /users?startIndex=50&limitIndex;=25
 *
 * AjaxProxy will also send sort and filter information to the server. Let's take a look at how this
 * looks with a more expressive Operation object:
 *
 *     var operation = Ext.create('Ext.data.Operation', {

 *             })
 *         ]
 *     });
 *
 * This is the type of object that is generated internally when loading a {@link Ext.data.Store Store}
 * with sorters and filters defined. By default the AjaxProxy will JSON encode the sorters and
 * filters, resulting in something like this (note that the url is escaped before sending the
 * request, but is left unescaped here for clarity):
 *
 *     var proxy = Ext.create('Ext.data.proxy.Ajax', {
 *         url: '/users'
 *     });
 *
 *     proxy.read(operation); // GET /users?sort=[{"property":"name","direction":"ASC"},{"property":"age","direction":"DESC"}]&filter;=[{"property":"eyeColor","value":"brown"}]
 *
 * We can again customize how this is created by supplying a few configuration options. Let's say
 * our server is set up to receive sorting information is a format like "sortBy=name#ASC,age#DESC".
 * We can configure AjaxProxy to provide that format like this:
 *
 *      var proxy = Ext.create('Ext.data.proxy.Ajax', {
 *          url: '/users',
 *          sortParam: 'sortBy',
 *          filterParam: 'filterBy',
 *
 *          // our custom implementation of sorter encoding - turns our sorters into "name#ASC,age#DESC"
 *          encodeSorters: function(sorters) {
 *              var length   = sorters.length,
 *                  sortStrs = [],
 *                  sorter, i;
 *
 *              for (i = 0; i < length; i++) {
 *                  sorter = sorters[i];
 *
 *                  sortStrs[i] = sorter.property + '#' + sorter.direction;
 *              }
 *
 *              return sortStrs.join(",");
 *          }
 *      });
 *
 *      proxy.read(operation); // GET /users?sortBy=name#ASC,age#DESC&filterBy;=[{"property":"eyeColor","value":"brown"}]
 *
 * We can also provide a custom {@link #encodeFilters} function to encode our filters.
 *
 * @constructor
 * Note that if this HttpProxy is being used by a {@link Ext.data.Store Store}, then the Store's
 * call to {@link Ext.data.Store#method-load load} will override any specified callback and params
 * options. In this case, use the {@link Ext.data.Store Store}'s events to modify parameters, or
 * react to loading events.
 *
 * @param {Object} config (optional) Config object.
 * If an options parameter is passed, the singleton {@link Ext.Ajax} object will be used to
 * make the request.

/**
 * @author Ed Spencer
 * @aside guide models
 *
 * Associations enable you to express relationships between different {@link Ext.data.Model Models}. Let's say we're
 * writing an ecommerce system where Users can make Orders - there's a relationship between these Models that we can
 * express like this:
 *
 *     Ext.define('MyApp.model.User', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: ['id', 'name', 'email'],
 *             hasMany: {
 *                 model: 'MyApp.model.Order',
 *                 name: 'orders'
 *             }
 *         }
 *     });
 *
 *     Ext.define('MyApp.model.Order', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: ['id', 'user_id', 'status', 'price'],
 *             belongsTo: 'MyApp.model.User'
 *         }
 *     });
 *
 * We've set up two models - User and Order - and told them about each other. You can set up as many associations on
 * each Model as you need using the two default types - {@link Ext.data.association.HasMany hasMany} and
 * {@link Ext.data.association.BelongsTo belongsTo}. There's much more detail on the usage of each of those inside their
 * documentation pages. If you're not familiar with Models already, {@link Ext.data.Model there is plenty on those too}.
 *
 * ## Further Reading
 *
 * - {@link Ext.data.association.HasMany hasMany associations}
 * - {@link Ext.data.association.BelongsTo belongsTo associations}
 * - {@link Ext.data.association.HasOne hasOne associations}
 * - {@link Ext.data.Model using Models}
 *
 * ### Self-associating Models
 *
 * We can also have models that create parent/child associations between the same type. Below is an example, where
 * groups can be nested inside other groups:
 *
 *     // Server Data
 *     {
 *         "groups": {
 *             "id": 10,
 *             "parent_id": 100,
 *             "name": "Main Group",
 *             "parent_group": {
 *                 "id": 100,
 *                 "parent_id": null,
 *                 "name": "Parent Group"
 *             },
 *             "nested" : {
 *                 "child_groups": [{
 *                     "id": 2,
 *                     "parent_id": 10,
 *                     "name": "Child Group 1"
 *                 },{
 *                     "id": 3,
 *                     "parent_id": 10,
 *                     "name": "Child Group 2"
 *                 },{
 *                     "id": 4,
 *                     "parent_id": 10,
 *                     "name": "Child Group 3"
 *                 }]
 *             }
 *         }
 *     }
 *
 *     // Client code
 *     Ext.define('MyApp.model.Group', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['id', 'parent_id', 'name'],
 *             proxy: {

 * General purpose inflector class that {@link #pluralize pluralizes}, {@link #singularize singularizes} and

 *
 * ## Customization
 *
 * The Inflector comes with a default set of US English pluralization rules. These can be augmented with additional
 * rules if the default rules do not meet your application's requirements, or swapped out entirely for other languages.
 * Here is how we might add a rule that pluralizes "ox" to "oxen":
 *
 *     Ext.util.Inflector.plural(/^(ox)$/i, "$1en");
 *
 * Each rule consists of two items - a regular expression that matches one or more rules, and a replacement string.
 * In this case, the regular expression will only match the string "ox", and will replace that match with "oxen".
 * Here's how we could add the inverse rule:
 *
 *     Ext.util.Inflector.singular(/^(ox)en$/i, "$1");
 *
 * __Note:__ The ox/oxen rules are present by default.

/**
 * @aside guide models
 *
 * Represents a one-to-many relationship between two models. Usually created indirectly via a model definition:
 *
 *     Ext.define('Product', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 {name: 'id',      type: 'int'},
 *                 {name: 'user_id', type: 'int'},
 *                 {name: 'name',    type: 'string'}
 *             ]
 *         }
 *     });
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 {name: 'id',   type: 'int'},
 *                 {name: 'name', type: 'string'}
 *             ],
 *             // we can use the hasMany shortcut on the model to create a hasMany association
 *             hasMany: {model: 'Product', name: 'products'}
 *         }
 *     });
 *
 * `
 *
 * Above we created Product and User models, and linked them by saying that a User hasMany Products. This gives us a new
 * function on every User instance, in this case the function is called 'products' because that is the name we specified
 * in the association configuration above.
 *
 * This new function returns a specialized {@link Ext.data.Store Store} which is automatically filtered to load only
 * Products for the given model instance:
 *
 *     //first, we load up a User with id of 1
 *     var user = Ext.create('User', {id: 1, name: 'Ed'});
 *
 *     //the user.products function was created automatically by the association and returns a {@link Ext.data.Store Store}
 *     //the created store is automatically scoped to the set of Products for the User with id of 1
 *     var products = user.products();
 *
 *     //we still have all of the usual Store functions, for example it's easy to add a Product for this User
 *     products.add({
 *         name: 'Another Product'
 *     });
 *
 *     //saves the changes to the store - this automatically sets the new Product's user_id to 1 before saving
 *     products.sync();
 *
 * The new Store is only instantiated the first time you call products() to conserve memory and processing time, though
 * calling products() a second time returns the same store instance.
 *
 * _Custom filtering_
 *
 * The Store is automatically furnished with a filter - by default this filter tells the store to only return records
 * where the associated model's foreign key matches the owner model's primary key. For example, if a User with ID = 100
 * hasMany Products, the filter loads only Products with user_id == 100.
 *
 * Sometimes we want to filter by another field - for example in the case of a Twitter search application we may have
 * models for Search and Tweet:
 *
 *     Ext.define('Search', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 'id', 'query'
 *             ],
 *
 *             hasMany: {
 *                 model: 'Tweet',
 *                 name : 'tweets',
 *                 filterProperty: 'query'
 *             }
 *         }
 *     });
 *
 *     Ext.define('Tweet', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 'id', 'text', 'from_user'
 *             ]
 *         }
 *     });
 *
 *     //returns a Store filtered by the filterProperty
 *     var store = new Search({query: 'Sencha Touch'}).tweets();
 *
 * The tweets association above is filtered by the query property by setting the {@link #filterProperty}, and is
 * equivalent to this:
 *
 *     var store = Ext.create('Ext.data.Store', {
 *         model: 'Tweet',
 *         filters: [
 *             {
 *                 property: 'query',
 *                 value   : 'Sencha Touch'
 *             }
 *         ]
 *     });

/**
 * @author Ed Spencer
 * @aside guide models
 *
 * Represents a many to one association with another model. The owner model is expected to have
 * a foreign key which references the primary key of the associated model:
 *
 *     Ext.define('Category', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 { name: 'id',   type: 'int' },
 *                 { name: 'name', type: 'string' }
 *             ]
 *         }
 *     });
 *
 *     Ext.define('Product', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 { name: 'id',          type: 'int' },
 *                 { name: 'category_id', type: 'int' },
 *                 { name: 'name',        type: 'string' }
 *             ],
 *             // we can use the belongsTo shortcut on the model to create a belongsTo association
 *             associations: { type: 'belongsTo', model: 'Category' }
 *         }
 *     });
 *
 * In the example above we have created models for Products and Categories, and linked them together
 * by saying that each Product belongs to a Category. This automatically links each Product to a Category
 * based on the Product's category_id, and provides new functions on the Product model:
 *
 * ## Generated getter function
 *
 * The first function that is added to the owner model is a getter function:
 *
 *     var product = new Product({
 *         id: 100,
 *         category_id: 20,
 *         name: 'Sneakers'
 *     });
 *
 *     product.getCategory(function(category, operation) {
 *         // do something with the category object
 *         alert(category.get('id')); // alerts 20
 *     }, this);
 *
 * The getCategory function was created on the Product model when we defined the association. This uses the
 * Category's configured {@link Ext.data.proxy.Proxy proxy} to load the Category asynchronously, calling the provided
 * callback when it has loaded.
 *
 * The new getCategory function will also accept an object containing success, failure and callback properties
 * - callback will always be called, success will only be called if the associated model was loaded successfully
 * and failure will only be called if the associated model could not be loaded:
 *
 *     product.getCategory({
 *         reload: true, // force a reload if the owner model is already cached
 *         callback: function(category, operation) {}, // a function that will always be called
 *         success : function(category, operation) {}, // a function that will only be called if the load succeeded
 *         failure : function(category, operation) {}, // a function that will only be called if the load did not succeed
 *         scope   : this // optionally pass in a scope object to execute the callbacks in
 *     });
 *
 * In each case above the callbacks are called with two arguments - the associated model instance and the
 * {@link Ext.data.Operation operation} object that was executed to load that instance. The Operation object is
 * useful when the instance could not be loaded.
 *
 * Once the getter has been called on the model, it will be cached if the getter is called a second time. To
 * force the model to reload, specify reload: true in the options object.
 *
 * ## Generated setter function
 *
 * The second generated function sets the associated model instance - if only a single argument is passed to
 * the setter then the following two calls are identical:
 *
 *     // this call...
 *     product.setCategory(10);
 *
 *     // is equivalent to this call:
 *     product.set('category_id', 10);
 *
 * An instance of the owner model can also be passed as a parameter.
 *
 * If we pass in a second argument, the model will be automatically saved and the second argument passed to
 * the owner model's {@link Ext.data.Model#save save} method:
 *
 *     product.setCategory(10, function(product, operation) {
 *         // the product has been saved
 *         alert(product.get('category_id')); //now alerts 10
 *     });
 *
 *     //alternative syntax:
 *     product.setCategory(10, {
 *         callback: function(product, operation) {}, // a function that will always be called
 *         success : function(product, operation) {}, // a function that will only be called if the load succeeded
 *         failure : function(product, operation) {}, // a function that will only be called if the load did not succeed
 *         scope   : this //optionally pass in a scope object to execute the callbacks in
 *     });
 *
 * ## Customization
 *
 * Associations reflect on the models they are linking to automatically set up properties such as the
 * {@link #primaryKey} and {@link #foreignKey}. These can alternatively be specified:
 *
 *     Ext.define('Product', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 // ...
 *             ],
 *
 *             associations: [
 *                 { type: 'belongsTo', model: 'Category', primaryKey: 'unique_id', foreignKey: 'cat_id' }
 *             ]
 *         }
 *     });
 *
 * Here we replaced the default primary key (defaults to 'id') and foreign key (calculated as 'category_id')
 * with our own settings. Usually this will not be needed.

/**
 * @aside guide models
 *
 * Represents a one to one association with another model. The owner model is expected to have
 * a foreign key which references the primary key of the associated model:
 *
 *     Ext.define('Person', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 { name: 'id', type: 'int' },
 *                 { name: 'name', type: 'string' },
 *                 { name: 'address_id', type: 'int'}
 *             ],
 *
 *             // we can use the hasOne shortcut on the model to create a hasOne association
 *             associations: { type: 'hasOne', model: 'Address' }
 *         }
 *     });
 *
 *     Ext.define('Address', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 { name: 'id', type: 'int' },
 *                 { name: 'number', type: 'string' },
 *                 { name: 'street', type: 'string' },
 *                 { name: 'city', type: 'string' },
 *                 { name: 'zip', type: 'string' }
 *             ]
 *         }
 *     });
 *
 * In the example above we have created models for People and Addresses, and linked them together
 * by saying that each Person has a single Address. This automatically links each Person to an Address
 * based on the Persons address_id, and provides new functions on the Person model:
 *
 * ## Generated getter function
 *
 * The first function that is added to the owner model is a getter function:
 *
 *     var person = Ext.create('Person', {
 *         id: 100,
 *         address_id: 20,
 *         name: 'John Smith'
 *     });
 *
 *     person.getAddress(function(address, operation) {
 *         // do something with the address object
 *         alert(address.get('id')); // alerts 20
 *     }, this);
 *
 * The getAddress function was created on the Person model when we defined the association. This uses the
 * Persons configured {@link Ext.data.proxy.Proxy proxy} to load the Address asynchronously, calling the provided
 * callback when it has loaded.
 *
 * The new getAddress function will also accept an object containing success, failure and callback properties
 * - callback will always be called, success will only be called if the associated model was loaded successfully
 * and failure will only be called if the associated model could not be loaded:
 *
 *     person.getAddress({
 *         reload: true, // force a reload if the owner model is already cached
 *         callback: function(address, operation) {}, // a function that will always be called
 *         success : function(address, operation) {}, // a function that will only be called if the load succeeded
 *         failure : function(address, operation) {}, // a function that will only be called if the load did not succeed
 *         scope   : this // optionally pass in a scope object to execute the callbacks in
 *     });
 *
 * In each case above the callbacks are called with two arguments - the associated model instance and the
 * {@link Ext.data.Operation operation} object that was executed to load that instance. The Operation object is
 * useful when the instance could not be loaded.
 *
 * Once the getter has been called on the model, it will be cached if the getter is called a second time. To
 * force the model to reload, specify reload: true in the options object.
 *
 * ## Generated setter function
 *
 * The second generated function sets the associated model instance - if only a single argument is passed to
 * the setter then the following two calls are identical:
 *
 *     // this call...
 *     person.setAddress(10);
 *
 *     // is equivalent to this call:
 *     person.set('address_id', 10);
 *
 * An instance of the owner model can also be passed as a parameter.
 *
 * If we pass in a second argument, the model will be automatically saved and the second argument passed to
 * the owner model's {@link Ext.data.Model#save save} method:
 *
 *     person.setAddress(10, function(address, operation) {
 *         // the address has been saved
 *         alert(address.get('address_id')); //now alerts 10
 *     });
 *
 *     //alternative syntax:
 *     person.setAddress(10, {
 *         callback: function(address, operation) {}, // a function that will always be called
 *         success : function(address, operation) {}, // a function that will only be called if the load succeeded
 *         failure : function(address, operation) {}, // a function that will only be called if the load did not succeed
 *         scope   : this //optionally pass in a scope object to execute the callbacks in
 *     });
 *
 * ## Customization
 *
 * Associations reflect on the models they are linking to automatically set up properties such as the
 * {@link #primaryKey} and {@link #foreignKey}. These can alternatively be specified:
 *
 *     Ext.define('Person', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 // ...
 *             ],
 *
 *             associations: [
 *                 { type: 'hasOne', model: 'Address', primaryKey: 'unique_id', foreignKey: 'addr_id' }
 *             ]
 *         }
 *     });
 *
 * Here we replaced the default primary key (defaults to 'id') and foreign key (calculated as 'address_id')
 * with our own settings. Usually this will not be needed.

 * @author Ed Spencer
 * @aside guide models
 *
 * A Model represents some object that your application manages. For example, one might define a Model for Users,
 * Products, Cars, or any other real-world object that we want to model in the system. Models are registered via the
 * {@link Ext.data.ModelManager model manager}, and are used by {@link Ext.data.Store stores}, which are in turn used by many
 * of the data-bound components in Ext.
 *
 * Models are defined as a set of fields and any arbitrary methods and properties relevant to the model. For example:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: [
 *                 {name: 'name',  type: 'string'},
 *                 {name: 'age',   type: 'int'},
 *                 {name: 'phone', type: 'string'},
 *                 {name: 'alive', type: 'boolean', defaultValue: true}
 *             ]
 *         },
 *
 *         changeName: function() {
 *             var oldName = this.get('name'),
 *                 newName = oldName + " The Barbarian";
 *
 *             this.set('name', newName);
 *         }
 *     });
 *
 * The fields array is turned into a {@link Ext.util.MixedCollection MixedCollection} automatically by the {@link
 * Ext.data.ModelManager ModelManager}, and all other functions and properties are copied to the new Model's prototype.
 *
 * Now we can create instances of our User model and call any model logic we defined:
 *
 *     var user = Ext.create('User', {
 *         name : 'Conan',
 *         age  : 24,
 *         phone: '555-555-5555'
 *     });
 *
 *     user.changeName();
 *     user.get('name'); // returns "Conan The Barbarian"
 *
 * # Validations
 *
 * Models have built-in support for validations, which are executed against the validator functions in {@link
 * Ext.data.validations} ({@link Ext.data.validations see all validation functions}). Validations are easy to add to
 * models:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: [
 *                 {name: 'name',     type: 'string'},
 *                 {name: 'age',      type: 'int'},
 *                 {name: 'phone',    type: 'string'},
 *                 {name: 'gender',   type: 'string'},
 *                 {name: 'username', type: 'string'},
 *                 {name: 'alive',    type: 'boolean', defaultValue: true}
 *             ],
 *
 *             validations: [
 *                 {type: 'presence',  field: 'age'},
 *                 {type: 'length',    field: 'name',     min: 2},
 *                 {type: 'inclusion', field: 'gender',   list: ['Male', 'Female']},
 *                 {type: 'exclusion', field: 'username', list: ['Admin', 'Operator']},
 *                 {type: 'format',    field: 'username', matcher: /([a-z]+)[0-9]{2,3}/}
 *             ]
 *         }
 *     });
 *
 * The validations can be run by simply calling the {@link #validate} function, which returns a {@link Ext.data.Errors}
 * object:
 *
 *     var instance = Ext.create('User', {
 *         name: 'Ed',
 *         gender: 'Male',
 *         username: 'edspencer'
 *     });
 *
 *     var errors = instance.validate();
 *
 * # Associations
 *
 * Models can have associations with other Models via {@link Ext.data.association.HasOne},
 * {@link Ext.data.association.BelongsTo belongsTo} and {@link Ext.data.association.HasMany hasMany} associations.
 * For example, let's say we're writing a blog administration application which deals with Users, Posts and Comments.
 * We can express the relationships between these models like this:
 *
 *     Ext.define('Post', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: ['id', 'user_id'],
 *             belongsTo: 'User',
 *             hasMany  : {model: 'Comment', name: 'comments'}
 *         }
 *     });
 *
 *     Ext.define('Comment', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: ['id', 'user_id', 'post_id'],
 *             belongsTo: 'Post'
 *         }
 *     });
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: ['id'],
 *             hasMany: [
 *                 'Post',
 *                 {model: 'Comment', name: 'comments'}
 *             ]
 *         }
 *     });
 *
 * See the docs for {@link Ext.data.association.HasOne}, {@link Ext.data.association.BelongsTo} and
 * {@link Ext.data.association.HasMany} for details on the usage and configuration of associations.
 * Note that associations can also be specified like this:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: ['id'],
 *             associations: [
 *                 {type: 'hasMany', model: 'Post',    name: 'posts'},
 *                 {type: 'hasMany', model: 'Comment', name: 'comments'}
 *             ]
 *         }
 *     });
 *
 * # Using a Proxy
 *
 * Models are great for representing types of data and relationships, but sooner or later we're going to want to load or
 * save that data somewhere. All loading and saving of data is handled via a {@link Ext.data.proxy.Proxy Proxy}, which
 * can be set directly on the Model:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: ['id', 'name', 'email'],
 *             proxy: {
 *                 type: 'rest',
 *                 url : '/users'
 *             }
 *         }
 *     });
 *
 * Here we've set up a {@link Ext.data.proxy.Rest Rest Proxy}, which knows how to load and save data to and from a
 * RESTful backend. Let's see how this works:
 *
 *     var user = Ext.create('User', {name: 'Ed Spencer', email: 'ed@sencha.com'});
 *
 *     user.save(); //POST /users
 *
 * Calling {@link #save} on the new Model instance tells the configured RestProxy that we wish to persist this Model's
 * data onto our server. RestProxy figures out that this Model hasn't been saved before because it doesn't have an id,
 * and performs the appropriate action - in this case issuing a POST request to the url we configured (/users). We
 * configure any Proxy on any Model and always follow this API - see {@link Ext.data.proxy.Proxy} for a full list.
 *
 * Loading data via the Proxy is equally easy:
 *
 *     //get a reference to the User model class
 *     var User = Ext.ModelManager.getModel('User');
 *
 *     //Uses the configured RestProxy to make a GET request to /users/123
 *     User.load(123, {
 *         success: function(user) {
 *             console.log(user.getId()); //logs 123
 *         }
 *     });
 *
 * Models can also be updated and destroyed easily:
 *
 *     //the user Model we loaded in the last snippet:
 *     user.set('name', 'Edward Spencer');
 *
 *     //tells the Proxy to save the Model. In this case it will perform a PUT request to /users/123 as this Model already has an id
 *     user.save({
 *         success: function() {
 *             console.log('The User was updated');
 *         }
 *     });
 *
 *     //tells the Proxy to destroy the Model. Performs a DELETE request to /users/123
 *     user.erase({
 *         success: function() {
 *             console.log('The User was destroyed!');
 *         }
 *     });
 *
 * # Usage in Stores
 *
 * It is very common to want to load a set of Model instances to be displayed and manipulated in the UI. We do this by
 * creating a {@link Ext.data.Store Store}:
 *
 *     var store = Ext.create('Ext.data.Store', {
 *         model: 'User'
 *     });
 *
 *     //uses the Proxy we set up on Model to load the Store data
 *     store.load();
 *
 * A Store is just a collection of Model instances - usually loaded from a server somewhere. Store can also maintain a
 * set of added, updated and removed Model instances to be synchronized with the server via the Proxy. See the {@link
 * Ext.data.Store Store docs} for more information on Stores.

/**
 * @author Ed Spencer
 * @aside guide stores
 *
 * The Store class encapsulates a client side cache of {@link Ext.data.Model Model} objects. Stores load
 * data via a {@link Ext.data.proxy.Proxy Proxy}, and also provide functions for {@link #sort sorting},
 * {@link #filter filtering} and querying the {@link Ext.data.Model model} instances contained within it.
 *
 * Creating a Store is easy - we just tell it the Model and the Proxy to use to load and save its data:
 *
 *     // Set up a {@link Ext.data.Model model} to use in our Store
 *     Ext.define("User", {
 *         extend: "Ext.data.Model",
 *         config: {
 *             fields: [
 *                 {name: "firstName", type: "string"},
 *                 {name: "lastName",  type: "string"},
 *                 {name: "age",       type: "int"},
 *                 {name: "eyeColor",  type: "string"}
 *             ]
 *         }
 *     });
 *
 *     var myStore = Ext.create("Ext.data.Store", {
 *         model: "User",
 *         proxy: {
 *             type: "ajax",
 *             url : "/users.json",
 *             reader: {
 *                 type: "json",
 *                 rootProperty: "users"
 *             }
 *         },
 *         autoLoad: true
 *     });
 *
 *     Ext.create("Ext.List", {
 *         fullscreen: true,
 *         store: myStore,
 *         itemTpl: "{lastName}, {firstName} ({age})"
 *     });
 *
 * In the example above we configured an AJAX proxy to load data from the url '/users.json'. We told our Proxy
 * to use a {@link Ext.data.reader.Json JsonReader} to parse the response from the server into Model object -
 * {@link Ext.data.reader.Json see the docs on JsonReader} for details.
 *
 * The external data file, _/users.json_, is as follows:
 *
 *     {
 *         "success": true,
 *         "users": [
 *             {
 *                 "firstName": "Tommy",
 *                 "lastName": "Maintz",
 *                 "age": 24,
 *                 "eyeColor": "green"
 *             },
 *             {
 *                 "firstName": "Aaron",
 *                 "lastName": "Conran",
 *                 "age": 26,
 *                 "eyeColor": "blue"
 *             },
 *             {
 *                 "firstName": "Jamie",
 *                 "lastName": "Avins",
 *                 "age": 37,
 *                 "eyeColor": "brown"
 *             }
 *         ]
 *     }
 *
 * ## Inline data
 *
 * Stores can also load data inline. Internally, Store converts each of the objects we pass in as {@link #cfg-data}
 * into Model instances:
 *
 *     @example
 *     // Set up a model to use in our Store
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 {name: 'firstName', type: 'string'},
 *                 {name: 'lastName',  type: 'string'},
 *                 {name: 'age',       type: 'int'},
 *                 {name: 'eyeColor',  type: 'string'}
 *             ]
 *         }
 *     });
 *
 *     Ext.create("Ext.data.Store", {
 *         storeId: "usersStore",
 *         model: "User",
 *         data : [
 *             {firstName: "Ed",    lastName: "Spencer"},
 *             {firstName: "Tommy", lastName: "Maintz"},
 *             {firstName: "Aaron", lastName: "Conran"},
 *             {firstName: "Jamie", lastName: "Avins"}
 *         ]
 *     });
 *
 *     Ext.create("Ext.List", {
 *         fullscreen: true,
 *         store: "usersStore",
 *         itemTpl: "{lastName}, {firstName}"
 *     });
 *
 * Loading inline data using the method above is great if the data is in the correct format already (e.g. it doesn't need
 * to be processed by a {@link Ext.data.reader.Reader reader}). If your inline data requires processing to decode the data structure,
 * use a {@link Ext.data.proxy.Memory MemoryProxy} instead (see the {@link Ext.data.proxy.Memory MemoryProxy} docs for an example).
 *
 * Additional data can also be loaded locally using {@link #method-add}.
 *
 * ## Loading Nested Data
 *
 * Applications often need to load sets of associated data - for example a CRM system might load a User and her Orders.
 * Instead of issuing an AJAX request for the User and a series of additional AJAX requests for each Order, we can load a nested dataset
 * and allow the Reader to automatically populate the associated models. Below is a brief example, see the {@link Ext.data.reader.Reader} intro
 * documentation for a full explanation:
 *
 *     // Set up a model to use in our Store
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 {name: 'name', type: 'string'},
 *                 {name: 'id',   type: 'int'}
 *             ]
 *         }
 *     });
 *
 *     var store = Ext.create('Ext.data.Store', {
 *         autoLoad: true,
 *         model: "User",
 *         proxy: {
 *             type: 'ajax',
 *             url : 'users.json',
 *             reader: {
 *                 type: 'json',
 *                 rootProperty: 'users'
 *             }
 *         }
 *     });
 *
 *     Ext.create("Ext.List", {
 *         fullscreen: true,
 *         store: store,
 *         itemTpl: "{name} (id: {id})"
 *     });
 *
 * Which would consume a response like this:
 *

 *
 * ## Filtering and Sorting
 *
 * Stores can be sorted and filtered - in both cases either remotely or locally. The {@link #sorters} and {@link #filters} are
 * held inside {@link Ext.util.MixedCollection MixedCollection} instances to make them easy to manage. Usually it is sufficient to
 * either just specify sorters and filters in the Store configuration or call {@link #sort} or {@link #filter}:
 *
 *     // Set up a model to use in our Store
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 {name: 'firstName', type: 'string'},
 *                 {name: 'lastName', type: 'string'},
 *                 {name: 'age',   type: 'int'}
 *             ]
 *         }
 *     });
 *
 *     var store = Ext.create("Ext.data.Store", {
 *         autoLoad: true,
 *         model: "User",
 *         proxy: {
 *             type: "ajax",
 *             url : "users.json",
 *             reader: {
 *                 type: "json",
 *                 rootProperty: "users"
 *             }
 *         },
 *         sorters: [
 *             {
 *                 property : "age",
 *                 direction: "DESC"
 *             },
 *             {
 *                 property : "firstName",
 *                 direction: "ASC"
 *             }
 *         ],
 *         filters: [
 *             {
 *                 property: "firstName",
 *                 value: /Jamie/
 *             }
 *         ]
 *     });
 *
 *     Ext.create("Ext.List", {
 *         fullscreen: true,
 *         store: store,
 *         itemTpl: "{lastName}, {firstName} ({age})"
 *     });
 *
 * And the data file, _users.json_, is as follows:
 *
 *     {
 *         "success": true,
 *         "users": [
 *             {
 *                 "firstName": "Tommy",
 *                 "lastName": "Maintz",
 *                 "age": 24
 *             },
 *             {
 *                 "firstName": "Aaron",
 *                 "lastName": "Conran",
 *                 "age": 26
 *             },
 *             {
 *                 "firstName": "Jamie",
 *                 "lastName": "Avins",
 *                 "age": 37
 *             }
 *         ]
 *     }
 *
 * The new Store will keep the configured sorters and filters in the MixedCollection instances mentioned above. By default, sorting
 * and filtering are both performed locally by the Store - see {@link #remoteSort} and {@link #remoteFilter} to allow the server to
 * perform these operations instead.
 *
 * Filtering and sorting after the Store has been instantiated is also easy. Calling {@link #filter} adds another filter to the Store
 * and automatically filters the dataset (calling {@link #filter} with no arguments simply re-applies all existing filters). Note that by
 * default your sorters are automatically reapplied if using local sorting.
 *
 *     store.filter('eyeColor', 'Brown');
 *
 * Change the sorting at any time by calling {@link #sort}:
 *
 *     store.sort('height', 'ASC');
 *
 * Note that all existing sorters will be removed in favor of the new sorter data (if {@link #sort} is called with no arguments,
 * the existing sorters are just reapplied instead of being removed). To keep existing sorters and add new ones, just add them
 * to the MixedCollection:
 *
 *     store.sorters.add(new Ext.util.Sorter({
 *         property : 'shoeSize',
 *         direction: 'ASC'
 *     }));
 *
 *     store.sort();
 *
 * ## Registering with StoreManager
 *
 * Any Store that is instantiated with a {@link #storeId} will automatically be registered with the {@link Ext.data.StoreManager StoreManager}.
 * This makes it easy to reuse the same store in multiple views:
 *
 *     // this store can be used several times
 *     Ext.create('Ext.data.Store', {
 *         model: 'User',
 *         storeId: 'usersStore'
 *     });
 *
 *     Ext.create('Ext.List', {
 *         store: 'usersStore'
 *         // other config goes here
 *     });
 *
 *     Ext.create('Ext.view.View', {
 *         store: 'usersStore'
 *         // other config goes here
 *     });
 *
 * ## Further Reading
 *
 * Stores are backed up by an ecosystem of classes that enables their operation. To gain a full understanding of these
 * pieces and how they fit together, see:
 *
 *  - {@link Ext.data.proxy.Proxy Proxy} - overview of what Proxies are and how they are used
 *  - {@link Ext.data.Model Model} - the core class in the data package
 *  - {@link Ext.data.reader.Reader Reader} - used by any subclass of {@link Ext.data.proxy.Server ServerProxy} to read a response

/**
 * Ext.Direct aims to streamline communication between the client and server by providing a single interface that
 * reduces the amount of common code typically required to validate data and handle returned data packets (reading data,
 * error conditions, etc).
 *
 * The Ext.direct namespace includes several classes for a closer integration with the server-side. The Ext.data
 * namespace also includes classes for working with Ext.data.Stores which are backed by data from an Ext.Direct method.
 *
 * # Specification
 *
 * For additional information consult the [Ext.Direct Specification](http://sencha.com/products/extjs/extdirect).
 *
 * # Providers
 *
 * Ext.Direct uses a provider architecture, where one or more providers are used to transport data to and from the
 * server. There are several providers that exist in the core at the moment:
 *
 * - {@link Ext.direct.JsonProvider JsonProvider} for simple JSON operations
 * - {@link Ext.direct.PollingProvider PollingProvider} for repeated requests
 * - {@link Ext.direct.RemotingProvider RemotingProvider} exposes server side on the client.
 *
 * A provider does not need to be invoked directly, providers are added via {@link Ext.direct.Manager}.{@link #addProvider}.
 *
 * # Router
 *
 * Ext.Direct utilizes a "router" on the server to direct requests from the client to the appropriate server-side
 * method. Because the Ext.Direct API is completely platform-agnostic, you could completely swap out a Java based server
 * solution and replace it with one that uses C# without changing the client side JavaScript at all.
 *
 * # Server side events
 *
 * Custom events from the server may be handled by the client by adding listeners, for example:
 *
 *     {"type":"event","name":"message","data":"Successfully polled at: 11:19:30 am"}
 *
 *     // add a handler for a 'message' event sent by the server
 *     Ext.direct.Manager.on('message', function(e){
 *         out.append(String.format('<p><i>{0}</i></p>', e.data));
 *         out.el.scrollTo('t', 100000, true);
 *     });

/**
 * @aside guide proxies
 *
 * This class is used to send requests to the server using {@link Ext.direct.Manager Ext.Direct}. When a
 * request is made, the transport mechanism is handed off to the appropriate
 * {@link Ext.direct.RemotingProvider Provider} to complete the call.
 *
 * # Specifying the function
 *
 * This proxy expects a Direct remoting method to be passed in order to be able to complete requests.
 * This can be done by specifying the {@link #directFn} configuration. This will use the same direct
 * method for all requests. Alternatively, you can provide an {@link #api} configuration. This
 * allows you to specify a different remoting method for each CRUD action.
 *
 * # Parameters
 *
 * This proxy provides options to help configure which parameters will be sent to the server.
 * By specifying the {@link #paramsAsHash} option, it will send an object literal containing each
 * of the passed parameters. The {@link #paramOrder} option can be used to specify the order in which
 * the remoting method parameters are passed.
 *
 * # Example Usage
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['firstName', 'lastName'],

 * @aside guide stores
 *
 * The TreeStore is a store implementation that allows for nested data.
 *
 * It provides convenience methods for loading nodes, as well as the ability to use
 * the hierarchical tree structure combined with a store. This class also relays many events from
 * the Tree for convenience.
 *
 * # Using Models
 *
 * If no Model is specified, an implicit model will be created that implements {@link Ext.data.NodeInterface}.
 * The standard Tree fields will also be copied onto the Model for maintaining their state. These fields are listed
 * in the {@link Ext.data.NodeInterface} documentation.
 *
 * # Reading Nested Data
 *
 * For the tree to read nested data, the {@link Ext.data.reader.Reader} must be configured with a root property,
 * so the reader can find nested data for each node. If a root is not specified, it will default to
 * 'children'.

 * This class generates UUID's according to RFC 4122. This class has a default id property.
 * This means that a single instance is shared unless the id property is overridden. Thus,

 *
 *     Ext.define('MyApp.data.MyModelX', {
 *         extend: 'Ext.data.Model',

 *
 *     Ext.define('MyApp.data.MyModelY', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             identifier: 'uuid'
 *         }
 *     });
 *
 * This allows all models using this class to share a commonly configured instance.
 *
 * # Using Version 1 ("Sequential") UUID's
 *
 * If a server can provide a proper timestamp and a "cryptographic quality random number"
 * (as described in RFC 4122), the shared instance can be configured as follows:
 *
 *     Ext.data.identifier.Uuid.Global.reconfigure({
 *         version: 1,
 *         clockSeq: clock, // 14 random bits
 *         salt: salt,      // 48 secure random bits (the Node field)
 *         timestamp: ts    // timestamp per Section 4.1.4
 *     });
 *
 *     // or these values can be split into 32-bit chunks:
 *
 *     Ext.data.identifier.Uuid.Global.reconfigure({
 *         version: 1,
 *         clockSeq: clock,
 *         salt: { lo: saltLow32, hi: saltHigh32 },
 *         timestamp: { lo: timestampLow32, hi: timestamptHigh32 }
 *     });
 *
 * This approach improves the generator's uniqueness by providing a valid timestamp and
 * higher quality random data. Version 1 UUID's should not be used unless this information
 * can be provided by a server and care should be taken to avoid caching of this data.
 *
 * See [http://www.ietf.org/rfc/rfc4122.txt](http://www.ietf.org/rfc/rfc4122.txt) for details.

/**
 * @author Ed Spencer
 * @aside guide proxies
 *
 * The JsonP proxy is useful when you need to load data from a domain other than the one your application is running on. If
 * your application is running on http://domainA.com it cannot use {@link Ext.data.proxy.Ajax Ajax} to load its data
 * from http://domainB.com because cross-domain ajax requests are prohibited by the browser.
 *
 * We can get around this using a JsonP proxy. JsonP proxy injects a `<script>` tag into the DOM whenever an AJAX request
 * would usually be made. Let's say we want to load data from http://domainB.com/users - the script tag that would be
 * injected might look like this:
 *
 *     <script src="http://domainB.com/users?callback=someCallback"></script>
 *
 * When we inject the tag above, the browser makes a request to that url and includes the response as if it was any
 * other type of JavaScript include. By passing a callback in the url above, we're telling domainB's server that we want
 * to be notified when the result comes in and that it should call our callback function with the data it sends back. So
 * long as the server formats the response to look like this, everything will work:
 *
 *     someCallback({
 *         users: [
 *             {
 *                 id: 1,
 *                 name: "Ed Spencer",
 *                 email: "ed@sencha.com"
 *             }
 *         ]
 *     });
 *
 * As soon as the script finishes loading, the 'someCallback' function that we passed in the url is called with the JSON
 * object that the server returned.
 *
 * JsonP proxy takes care of all of this automatically. It formats the url you pass, adding the callback parameter
 * automatically. It even creates a temporary callback function, waits for it to be called and then puts the data into
 * the Proxy making it look just like you loaded it through a normal {@link Ext.data.proxy.Ajax AjaxProxy}. Here's how
 * we might set that up:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['id', 'name', 'email']
 *         }
 *     });
 *
 *     var store = Ext.create('Ext.data.Store', {
 *         model: 'User',
 *         proxy: {
 *             type: 'jsonp',
 *             url : 'http://domainB.com/users'
 *         }
 *     });
 *
 *     store.load();
 *
 * That's all we need to do - JsonP proxy takes care of the rest. In this case the Proxy will have injected a script tag
 * like this:
 *
 *     <script src="http://domainB.com/users?callback=callback1"></script>
 *
 * # Customization
 *
 * This script tag can be customized using the {@link #callbackKey} configuration. For example:
 *
 *     var store = Ext.create('Ext.data.Store', {
 *         model: 'User',
 *         proxy: {
 *             type: 'jsonp',
 *             url : 'http://domainB.com/users',
 *             callbackKey: 'theCallbackFunction'
 *         }
 *     });
 *
 *     store.load();
 *
 * Would inject a script tag like this:
 *
 *     <script src="http://domainB.com/users?theCallbackFunction=callback1"></script>
 *
 * # Implementing on the server side
 *
 * The remote server side needs to be configured to return data in this format. Here are suggestions for how you might
 * achieve this using Java, PHP and ASP.net:
 *
 * Java:
 *
 *     boolean jsonP = false;
 *     String cb = request.getParameter("callback");
 *     if (cb != null) {
 *         jsonP = true;
 *         response.setContentType("text/javascript");
 *     } else {
 *         response.setContentType("application/x-json");
 *     }
 *     Writer out = response.getWriter();
 *     if (jsonP) {
 *         out.write(cb + "(");
 *     }
 *     out.print(dataBlock.toJsonString());
 *     if (jsonP) {
 *         out.write(");");
 *     }
 *
 * PHP:
 *
 *     $callback = $_REQUEST['callback'];
 *
 *     // Create the output object.
 *     $output = array('a' => 'Apple', 'b' => 'Banana');
 *
 *     //start output
 *     if ($callback) {
 *         header('Content-Type: text/javascript');
 *         echo $callback . '(' . json_encode($output) . ');';
 *     } else {
 *         header('Content-Type: application/x-json');
 *         echo json_encode($output);
 *     }
 *
 * ASP.net:
 *
 *     String jsonString = "{success: true}";
 *     String cb = Request.Params.Get("callback");
 *     String responseString = "";
 *     if (!String.IsNullOrEmpty(cb)) {
 *         responseString = cb + "(" + jsonString + ")";
 *     } else {
 *         responseString = jsonString;

 *
 * The LocalStorageProxy uses the new HTML5 localStorage API to save {@link Ext.data.Model Model} data locally on the
 * client browser. HTML5 localStorage is a key-value store (e.g. cannot save complex objects like JSON), so
 * LocalStorageProxy automatically serializes and deserializes data when saving and retrieving it.
 *
 * localStorage is extremely useful for saving user-specific information without needing to build server-side
 * infrastructure to support it. Let's imagine we're writing a Twitter search application and want to save the user's
 * searches locally so they can easily perform a saved search again later. We'd start by creating a Search model:
 *
 *     Ext.define('Search', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['id', 'query'],
 *             proxy: {
 *                 type: 'localstorage',
 *                 id  : 'twitter-Searches'
 *             }
 *         }
 *     });
 *
 * Our Search model contains just two fields - id and query - plus a Proxy definition. The only configuration we need to
 * pass to the LocalStorage proxy is an {@link #id}. This is important as it separates the Model data in this Proxy from
 * all others. The localStorage API puts all data into a single shared namespace, so by setting an id we enable
 * LocalStorageProxy to manage the saved Search data.
 *
 * Saving our data into localStorage is easy and would usually be done with a {@link Ext.data.Store Store}:
 *
 *     //our Store automatically picks up the LocalStorageProxy defined on the Search model
 *     var store = Ext.create('Ext.data.Store', {
 *         model: "Search"
 *     });
 *
 *     //loads any existing Search data from localStorage
 *     store.load();
 *
 *     //now add some Searches
 *     store.add({query: 'Sencha Touch'});
 *     store.add({query: 'Ext JS'});
 *
 *     //finally, save our Search data to localStorage
 *     store.sync();
 *
 * The LocalStorageProxy automatically gives our new Searches an id when we call store.sync(). It encodes the Model data
 * and places it into localStorage. We can also save directly to localStorage, bypassing the Store altogether:
 *
 *     var search = Ext.create('Search', {query: 'Sencha Animator'});
 *
 *     //uses the configured LocalStorageProxy to save the new Search to localStorage
 *     search.save();
 *
 * # Limitations
 *
 * If this proxy is used in a browser where local storage is not supported, the constructor will throw an error. A local
 * storage proxy requires a unique ID which is used as a key in which all record data are stored in the local storage
 * object.
 *
 * It's important to supply this unique ID as it cannot be reliably determined otherwise. If no id is provided but the
 * attached store has a storeId, the storeId will be used. If neither option is presented the proxy will throw an error.

 *
 * The Rest proxy is a specialization of the {@link Ext.data.proxy.Ajax AjaxProxy} which simply maps the four actions
 * (create, read, update and destroy) to RESTful HTTP verbs. For example, let's set up a {@link Ext.data.Model Model}
 * with an inline Rest proxy:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['id', 'name', 'email'],
 *
 *             proxy: {
 *                 type: 'rest',
 *                 url : '/users'
 *             }
 *         }
 *     });
 *
 * Now we can create a new User instance and save it via the Rest proxy. Doing this will cause the Proxy to send a POST
 * request to '/users':
 *
 *     var user = Ext.create('User', {name: 'Ed Spencer', email: 'ed@sencha.com'});
 *
 *     user.save(); //POST /users
 *
 * Let's expand this a little and provide a callback for the {@link Ext.data.Model#save} call to update the Model once
 * it has been created. We'll assume the creation went successfully and that the server gave this user an ID of 123:
 *
 *     user.save({
 *         success: function(user) {
 *             user.set('name', 'Khan Noonien Singh');
 *
 *             user.save(); //PUT /users/123
 *         }
 *     });
 *
 * Now that we're no longer creating a new Model instance, the request method is changed to an HTTP PUT, targeting the
 * relevant url for that user. Now let's delete this user, which will use the DELETE method:
 *
 *         user.erase(); //DELETE /users/123
 *
 * Finally, when we perform a load of a Model or Store, Rest proxy will use the GET method:
 *
 *     //1. Load via Store
 *
 *     //the Store automatically picks up the Proxy from the User model
 *     var store = Ext.create('Ext.data.Store', {
 *         model: 'User'
 *     });
 *
 *     store.load(); //GET /users
 *
 *     //2. Load directly from the Model
 *
 *     //GET /users/123
 *     Ext.ModelManager.getModel('User').load(123, {
 *         success: function(user) {
 *             console.log(user.getId()); //outputs 123
 *         }
 *     });
 *
 * # Url generation
 *
 * The Rest proxy is able to automatically generate the urls above based on two configuration options - {@link #appendId} and
 * {@link #format}. If appendId is true (it is by default) then Rest proxy will automatically append the ID of the Model
 * instance in question to the configured url, resulting in the '/users/123' that we saw above.
 *
 * If the request is not for a specific Model instance (e.g. loading a Store), the url is not appended with an id.
 * The Rest proxy will automatically insert a '/' before the ID if one is not already present.
 *
 *     new Ext.data.proxy.Rest({
 *         url: '/users',
 *         appendId: true //default
 *     });
 *
 *     // Collection url: /users
 *     // Instance url  : /users/123
 *
 * The Rest proxy can also optionally append a format string to the end of any generated url:
 *
 *     new Ext.data.proxy.Rest({
 *         url: '/users',
 *         format: 'json'
 *     });
 *
 *     // Collection url: /users.json
 *     // Instance url  : /users/123.json
 *
 * If further customization is needed, simply implement the {@link #buildUrl} method and add your custom generated url
 * onto the {@link Ext.data.Request Request} object that is passed to buildUrl. See [Rest proxy's implementation][1] for
 * an example of how to achieve this.
 *
 * Note that Rest proxy inherits from {@link Ext.data.proxy.Ajax AjaxProxy}, which already injects all of the sorter,
 * filter, group and paging options into the generated url. See the {@link Ext.data.proxy.Ajax AjaxProxy docs} for more
 * details.

/**
 * @author Ed Spencer
 * @aside guide proxies
 *
 * Proxy which uses HTML5 session storage as its data storage/retrieval mechanism. If this proxy is used in a browser
 * where session storage is not supported, the constructor will throw an error. A session storage proxy requires a
 * unique ID which is used as a key in which all record data are stored in the session storage object.
 *
 * It's important to supply this unique ID as it cannot be reliably determined otherwise. If no id is provided but the
 * attached store has a storeId, the storeId will be used. If neither option is presented the proxy will throw an error.
 *
 * Proxies are almost always used with a {@link Ext.data.Store store}:
 *
 *     new Ext.data.Store({
 *         proxy: {
 *             type: 'sessionstorage',
 *             id  : 'myProxyKey'
 *         }
 *     });
 *
 * Alternatively you can instantiate the Proxy directly:
 *
 *     new Ext.data.proxy.SessionStorage({
 *         id  : 'myOtherProxyKey'
 *     });
 *
 * Note that session storage is different to local storage (see {@link Ext.data.proxy.LocalStorage}) - if a browser
 * session is ended (e.g. by closing the browser) then all data in a SessionStorageProxy are lost. Browser restarts
 * don't affect the {@link Ext.data.proxy.LocalStorage} - the data are preserved.

/**
 * @author Ed Spencer
 * @class Ext.data.reader.Xml
 * @extends Ext.data.reader.Reader
 *
 * The XML Reader is used by a Proxy to read a server response that is sent back in XML format. This usually
 * happens as a result of loading a Store - for example we might create something like this:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['id', 'name', 'email']
 *         }
 *     });
 *
 *     var store = Ext.create('Ext.data.Store', {
 *         model: 'User',
 *         proxy: {
 *             type: 'ajax',
 *             url : 'users.xml',
 *             reader: {
 *                 type: 'xml',
 *                 record: 'user'
 *             }
 *         }
 *     });
 *
 * The example above creates a 'User' model. Models are explained in the {@link Ext.data.Model Model} docs if you're
 * not already familiar with them.
 *
 * We created the simplest type of XML Reader possible by simply telling our {@link Ext.data.Store Store}'s
 * {@link Ext.data.proxy.Proxy Proxy} that we want a XML Reader. The Store automatically passes the configured model to the
 * Store, so it is as if we passed this instead:
 *
 *     reader: {
 *         type : 'xml',
 *         model: 'User',
 *         record: 'user'
 *     }
 *
 * The reader we set up is ready to read data from our server - at the moment it will accept a response like this:
 *
 *     <?xml version="1.0" encoding="UTF-8"?>
 *     <user>
 *         <id>1</id>
 *         <name>Ed Spencer</name>
 *         <email>ed@sencha.com</email>
 *     </user>
 *     <user>
 *         <id>2</id>
 *         <name>Abe Elias</name>
 *         <email>abe@sencha.com</email>
 *     </user>
 *
 * The XML Reader uses the configured {@link #record} option to pull out the data for each record - in this case we
 * set record to 'user', so each `<user>` above will be converted into a User model.
 *
 * ## Reading other XML formats
 *
 * If you already have your XML format defined and it doesn't look quite like what we have above, you can usually
 * pass XmlReader a couple of configuration options to make it parse your format. For example, we can use the
 * {@link #rootProperty} configuration to parse data that comes back like this:
 *
 *     <?xml version="1.0" encoding="UTF-8"?>
 *     <users>
 *         <user>
 *             <id>1</id>
 *             <name>Ed Spencer</name>
 *             <email>ed@sencha.com</email>
 *         </user>
 *         <user>
 *             <id>2</id>
 *             <name>Abe Elias</name>
 *             <email>abe@sencha.com</email>
 *         </user>
 *     </users>
 *
 * To parse this we just pass in a {@link #rootProperty} configuration that matches the 'users' above:
 *
 *     reader: {
 *         type: 'xml',
 *         record: 'user',
 *         rootProperty: 'users'
 *     }
 *
 * Note that XmlReader doesn't care whether your {@link #rootProperty} and {@link #record} elements are nested deep
 * inside a larger structure, so a response like this will still work:
 *
 *     <?xml version="1.0" encoding="UTF-8"?>
 *     <deeply>
 *         <nested>
 *             <xml>
 *                 <users>
 *                     <user>
 *                         <id>1</id>
 *                         <name>Ed Spencer</name>
 *                         <email>ed@sencha.com</email>
 *                     </user>
 *                     <user>
 *                         <id>2</id>
 *                         <name>Abe Elias</name>
 *                         <email>abe@sencha.com</email>
 *                     </user>
 *                 </users>
 *             </xml>
 *         </nested>
 *     </deeply>
 *
 * ## Response metadata
 *
 * The server can return additional data in its response, such as the {@link #totalProperty total number of records}
 * and the {@link #successProperty success status of the response}. These are typically included in the XML response
 * like this:
 *
 *     <?xml version="1.0" encoding="UTF-8"?>
 *     <total>100</total>
 *     <success>true</success>
 *     <users>
 *         <user>
 *             <id>1</id>
 *             <name>Ed Spencer</name>
 *             <email>ed@sencha.com</email>
 *         </user>
 *         <user>
 *             <id>2</id>
 *             <name>Abe Elias</name>
 *             <email>abe@sencha.com</email>
 *         </user>
 *     </users>
 *
 * If these properties are present in the XML response they can be parsed out by the XmlReader and used by the
 * Store that loaded it. We can set up the names of these properties by specifying a final pair of configuration
 * options:
 *
 *     reader: {
 *         type: 'xml',
 *         rootProperty: 'users',
 *         totalProperty  : 'total',
 *         successProperty: 'success'
 *     }
 *
 * These final options are not necessary to make the Reader work, but can be useful when the server needs to report
 * an error or if it needs to indicate that there is a lot of data available of which only a subset is currently being
 * returned.
 *
 * ## Response format
 *
 * __Note:__ In order for the browser to parse a returned XML document, the Content-Type header in the HTTP
 * response must be set to "text/xml" or "application/xml". This is very important - the XmlReader will not
 * work correctly otherwise.

/**
 * @private
 *
 * This object handles communication between the WebView and Sencha's native shell.
 * Currently it has two primary responsibilities:
 *
 * 1. Maintaining unique string ids for callback functions, together with their scope objects
 * 2. Serializing given object data into HTTP GET request parameters
 *
 * As an example, to capture a photo from the device's camera, we use `Ext.device.Camera.capture()` like:
 *
 *     Ext.device.Camera.capture(
 *         function(dataUri){
 *             // Do something with the base64-encoded `dataUri` string
 *         },
 *         function(errorMessage) {
 *
 *         },
 *         callbackScope,
 *         {
 *             quality: 75,
 *             width: 500,
 *             height: 500
 *         }
 *     );
 *
 * Internally, `Ext.device.Communicator.send()` will then be invoked with the following argument:
 *
 *     Ext.device.Communicator.send({
 *         command: 'Camera#capture',
 *         callbacks: {
 *             onSuccess: function() {
 *                 // ...
 *             },
 *             onError: function() {
 *                 // ...
 *             }
 *         },
 *         scope: callbackScope,
 *         quality: 75,
 *         width: 500,
 *         height: 500
 *     });
 *
 * Which will then be transformed into a HTTP GET request, sent to native shell's local
 * HTTP server with the following parameters:
 *
 *     ?quality=75&width=500&height=500&command=Camera%23capture&onSuccess=3&onError=5
 *
 * Notice that `onSuccess` and `onError` have been converted into string ids (`3` and `5`
 * respectively) and maintained by `Ext.device.Communicator`.
 *
 * Whenever the requested operation finishes, `Ext.device.Communicator.invoke()` simply needs
 * to be executed from the native shell with the corresponding ids given before. For example:
 *
 *     Ext.device.Communicator.invoke('3', ['DATA_URI_OF_THE_CAPTURED_IMAGE_HERE']);
 *
 * will invoke the original `onSuccess` callback under the given scope. (`callbackScope`), with
 * the first argument of 'DATA_URI_OF_THE_CAPTURED_IMAGE_HERE'
 *
 * Note that `Ext.device.Communicator` maintains the uniqueness of each function callback and
 * its scope object. If subsequent calls to `Ext.device.Communicator.send()` have the same
 * callback references, the same old ids will simply be reused, which guarantee the best possible
 * performance for a large amount of repetitive calls.

/**
 * Provides a cross device way to get information about the device your application is running on. There are 3 different implementations:
 *
 * - Sencha Packager
 * - [PhoneGap](http://docs.phonegap.com/en/1.4.1/phonegap_device_device.md.html)
 * - Simulator
 *
 * ## Examples
 *
 * #### Device Information
 * 
 * Getting the device information:
 * 
 *     Ext.application({
 *         name: 'Sencha',
 *
 *         // Remember that the Ext.device.Device class *must* be required
 *         requires: ['Ext.device.Device'],
 * 
 *         launch: function() {
 *             alert([
 *                 'Device name: ' + Ext.device.Device.name,
 *                 'Device platform: ' + Ext.device.Device.platform,
 *                 'Device UUID: ' + Ext.device.Device.uuid
 *             ].join('\n'));
 *         }
 *     });
 *
 * ### Custom Scheme URLs
 * 
 * Using custom scheme URLs to application your application from other applications:
 *
 *     Ext.application({
 *         name: 'Sencha',
 *         requires: ['Ext.device.Device'],
 *         launch: function() {
 *             if (Ext.device.Device.scheme) {
 *                 // the application was opened via another application. Do something:
 *                 alert('Applicaton pened via another application: ' + Ext.device.Device.scheme.url);
 *             }
 *
 *             // Listen for future changes
 *             Ext.device.Device.on('schemeupdate', function(device, scheme) {
 *                 // the application was launched, closed, and then launched another from another application
 *                 // this means onReady wont be called again ('cause the application is already running in the 
 *                 // background) - but this event will be fired
 *                 alert('Applicated reopened via another application: ' + scheme.url);
 *             }, this);
 *         }
 *     });
 *
 * Of course, you must add add the custom URLs you would like to use when packaging your application. You can do this by adding
 * the following code into the `rawConfig` property inside your `package.json` file (Sencha Native Packager configuration file):
 * 
 *     {
 *         ...
 *         "rawConfig": "<key>CFBundleURLTypes</key><array><dict><key>CFBundleURLSchemes</key><array><string>sencha</string></array><key>CFBundleURLName</key><string>com.sencha.example</string></dict></array>"
 *         ...
 *     }
 *
 * You can change the available URL schemes and the application identifier above.
 * 
 * You can then test it by packaging and installing the application onto a device/iOS Simulator, opening Safari and typing: `sencha:testing`.
 * The application will launch and it will `alert` the URL you specified.
 *
 * **PLEASE NOTE: This currently only works with the Sencha Native Packager. If you attempt to listen to this event when packaged with 
 * PhoneGap or simply in the browser, it will not function.**

/**
 * Provides access to the native Geolocation API when running on a device. There are three implementations of this API:
 *
 * - Sencha Packager
 * - [PhoneGap](http://docs.phonegap.com/en/1.4.1/phonegap_device_device.md.html)
 * - Browser
 *
 * This class will automatically select the correct implementation depending on the device your application is running on.
 *
 * ## Examples
 *
 * Getting the current location:
 *
 *     Ext.device.Geolocation.getCurrentPosition({
 *         success: function(position) {
 *             console.log(position.coords);
 *         },
 *         failure: function() {
 *             console.log('something went wrong!');
 *         }
 *     });
 *
 * Watching the current location:
 *
 *     Ext.device.Geolocation.watchPosition({
 *         frequency: 3000, // Update every 3 seconds
 *         callback: function(position) {
 *             console.log('Position updated!', position.coords);
 *         },
 *         failure: function() {
 *             console.log('something went wrong!');
 *         }
 *     });

/**
 * The DelayedTask class provides a convenient way to "buffer" the execution of a method,
 * performing `setTimeout` where a new timeout cancels the old timeout. When called, the
 * task will wait the specified time period before executing. If during that time period,
 * the task is called again, the original call will be canceled. This continues so that
 * the function is only called a single time for each iteration.
 *
 * This method is especially useful for things like detecting whether a user has finished
 * typing in a text field. An example would be performing validation on a keypress. You can
 * use this class to buffer the keypress events for a certain number of milliseconds, and
 * perform only if they stop for that amount of time.
 *
 * Using {@link Ext.util.DelayedTask} is very simple:
 *
 *     //create the delayed task instance with our callback
 *     var task = Ext.create('Ext.util.DelayedTask', function() {
 *         console.log('callback!');
 *     });
 *
 *     task.delay(1500); //the callback function will now be called after 1500ms
 *
 *     task.cancel(); //the callback function will never be called now, unless we call delay() again
 *
 * ## Example
 *
 *     @example
 *     //create a textfield where we can listen to text
 *     var field = Ext.create('Ext.field.Text', {
 *         xtype: 'textfield',
 *         label: 'Length: 0'
 *     });
 *
 *     //add the textfield into a fieldset
 *     Ext.Viewport.add({
 *         xtype: 'formpanel',
 *         items: [{
 *             xtype: 'fieldset',
 *             items: [field],
 *             instructions: 'Type into the field and watch the count go up after 500ms.'
 *         }]
 *     });
 *
 *     //create our delayed task with a function that returns the fields length as the fields label
 *     var task = Ext.create('Ext.util.DelayedTask', function() {
 *         field.setLabel('Length: ' + field.getValue().length);
 *     });
 *
 *     // Wait 500ms before calling our function. If the user presses another key
 *     // during that 500ms, it will be canceled and we'll wait another 500ms.
 *     field.on('keyup', function() {
 *         task.delay(500);
 *     });
 *
 * @constructor

 * @param {Function} fn The default function to call.

/**
 * @aside guide forms
 *
 * The checkbox field is an enhanced version of the native browser checkbox and is great for enabling your user to
 * choose one or more items from a set (for example choosing toppings for a pizza order). It works like any other
 * {@link Ext.field.Field field} and is usually found in the context of a form:
 *
 * ## Example
 *
 *     @example miniphone preview
 *     var form = Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {

 *                 label: 'Tomato',
 *                 value: 'tomato',
 *                 checked: true
 *             },
 *             {
 *                 xtype: 'checkboxfield',
 *                 name : 'salami',
 *                 label: 'Salami'
 *             },
 *             {
 *                 xtype: 'toolbar',

 *                 items: [
 *                     { xtype: 'spacer' },

 *                                 values = form.getValues();
 *
 *                             Ext.Msg.alert(null,

 *             }
 *         ]
 *     });
 *
 *
 * The form above contains two check boxes - one for Tomato, one for Salami. We configured the Tomato checkbox to be
 * checked immediately on load, and the Salami checkbox to be unchecked. We also specified an optional text
 * {@link #value} that will be sent when we submit the form. We can get this value using the Form's
 * {@link Ext.form.Panel#getValues getValues} function, or have it sent as part of the data that is sent when the
 * form is submitted:
 *
 *     form.getValues(); //contains a key called 'tomato' if the Tomato field is still checked
 *     form.submit(); //will send 'tomato' in the form submission data

 *         ]
 *     });
 *     Ext.Viewport.add(picker);

 * ## Examples
 *
 *     @example miniphone preview
 *     var datePicker = Ext.create('Ext.picker.Date');
 *     Ext.Viewport.add(datePicker);
 *     datePicker.show();
 *
 * You may want to adjust the {@link #yearFrom} and {@link #yearTo} properties:
 *
 *     @example miniphone preview
 *     var datePicker = Ext.create('Ext.picker.Date', {
 *         yearFrom: 2000,
 *         yearTo  : 2015
 *     });
 *     Ext.Viewport.add(datePicker);
 *     datePicker.show();
 *
 * You can set the value of the {@link Ext.picker.Date} to the current date using `new Date()`:
 *
 *     @example miniphone preview
 *     var datePicker = Ext.create('Ext.picker.Date', {
 *         value: new Date()
 *     });
 *     Ext.Viewport.add(datePicker);
 *     datePicker.show();
 *
 * And you can hide the titles from each of the slots by using the {@link #useTitles} configuration:
 *
 *     @example miniphone preview
 *     var datePicker = Ext.create('Ext.picker.Date', {
 *         useTitles: false
 *     });
 *     Ext.Viewport.add(datePicker);
 *     datePicker.show();

/**
 * @aside guide forms
 *
 * This is a specialized field which shows a {@link Ext.picker.Date} when tapped. If it has a predefined value,
 * or a value is selected in the {@link Ext.picker.Date}, it will be displayed like a normal {@link Ext.field.Text}
 * (but not selectable/changable).
 *
 *     Ext.create('Ext.field.DatePicker', {
 *         label: 'Birthday',
 *         value: new Date()
 *     });
 *
 * {@link Ext.field.DatePicker} fields are very simple to implement, and have no required configurations.
 *
 * ## Examples
 *
 * It can be very useful to set a default {@link #value} configuration on {@link Ext.field.DatePicker} fields. In
 * this example, we set the {@link #value} to be the current date. You can also use the {@link #setValue} method to
 * update the value at any time.
 *
 *     @example miniphone preview
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 items: [
 *                     {
 *                         xtype: 'datepickerfield',
 *                         label: 'Birthday',
 *                         name: 'birthday',
 *                         value: new Date()
 *                     }
 *                 ]
 *             },
 *             {
 *                 xtype: 'toolbar',
 *                 docked: 'bottom',
 *                 items: [
 *                     { xtype: 'spacer' },

 *                         handler: function() {
 *                             var datePickerField = Ext.ComponentQuery.query('datepickerfield')[0];
 *
 *                             var randomNumber = function(from, to) {
 *                                 return Math.floor(Math.random() * (to - from + 1) + from);
 *                             };
 *
 *                             datePickerField.setValue({
 *                                 month: randomNumber(0, 11),
 *                                 day  : randomNumber(0, 28),
 *                                 year : randomNumber(1980, 2011)
 *                             });
 *                         }
 *                     },
 *                     { xtype: 'spacer' }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * When you need to retrieve the date from the {@link Ext.field.DatePicker}, you can either use the {@link #getValue} or
 * {@link #getFormattedValue} methods:
 *
 *     @example preview
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,

 *                 items: [
 *                     {
 *                         xtype: 'datepickerfield',
 *                         label: 'Birthday',
 *                         name: 'birthday',
 *                         value: new Date()
 *                     }
 *                 ]
 *             },
 *             {
 *                 xtype: 'toolbar',

 *                 items: [
 *                     {
 *                         xtype: 'emailfield',

 *                     },

 *                         label: 'Password',

 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * Or on its own, outside of a form:
 *
 *     Ext.create('Ext.field.Email', {
 *         label: 'Email address',
 *         value: 'prefilled@email.com'
 *     });
 *

 * provide, including getting and setting the value at runtime, validations and various events that are fired as the
 * user interacts with the component. Check out the {@link Ext.field.Text} docs to see the additional functionality

/**
 * @aside guide forms
 *
 * Hidden fields allow you to easily inject additional data into a {@link Ext.form.Panel form} without displaying
 * additional fields on the screen. This is often useful for sending dynamic or previously collected data back to the
 * server in the same request as the normal form submission. For example, here is how we might set up a form to send
 * back a hidden userId field:
 *
 *     @example
 *     var form = Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 title: 'Enter your name',
 *                 items: [
 *                     {
 *                         xtype: 'hiddenfield',
 *                         name: 'userId',
 *                         value: 123
 *                     },
 *                     {
 *                         xtype: 'checkboxfield',
 *                         label: 'Enable notifications',
 *                         name: 'notifications'
 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * In the form above we created two fields - a hidden field and a {@link Ext.field.Checkbox check box field}. Only the
 * check box will be visible, but both fields will be submitted. Hidden fields cannot be tabbed to - they are removed
 * from the tab index so when your user taps the next/previous field buttons the hidden field is skipped over.
 *
 * It's easy to read and update the value of a hidden field within a form. Using the example above, we can get a
 * reference to the hidden field and then set it to a new value in 2 lines of code:
 *
 *     var userId = form.down('hiddenfield')[0];
 *     userId.setValue(1234);

 * The Number field creates an HTML5 number input and is usually created inside a form. Because it creates an HTML

 * only accepts numerical input and also provides additional spinner UI that increases or decreases the current value
 * by a configured {@link #stepValue step value}. Here's how we might use one in a form:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 title: 'How old are you?',
 *                 items: [
 *                     {
 *                         xtype: 'numberfield',
 *                         label: 'Age',
 *                         minValue: 18,
 *                         maxValue: 150,
 *                         name: 'age'
 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * Or on its own, outside of a form:
 *
 *     Ext.create('Ext.field.Number', {
 *         label: 'Age',
 *         value: '26'
 *     });
 *
 * ## minValue, maxValue and stepValue
 *
 * The {@link #minValue} and {@link #maxValue} configurations are self-explanatory and simply constrain the value
 * entered to the range specified by the configured min and max values. The other option exposed by this component
 * is {@link #stepValue}, which enables you to set how much the value changes every time the up and down spinners
 * are tapped on. For example, to create a salary field that ticks up and down by $1,000 each tap we can do this:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 title: 'Are you rich yet?',
 *                 items: [
 *                     {
 *                         xtype: 'numberfield',
 *                         label: 'Salary',
 *                         value: 30000,
 *                         minValue: 25000,
 *                         maxValue: 50000,
 *                         stepValue: 1000
 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * This creates a field that starts with a value of $30,000, steps up and down in $1,000 increments and will not go
 * beneath $25,000 or above $50,000.
 *
 * Because number field inherits from {@link Ext.field.Text textfield} it gains all of the functionality that text
 * fields provide, including getting and setting the value at runtime, validations and various events that are fired as
 * the user interacts with the component. Check out the {@link Ext.field.Text} docs to see the additional functionality

 * The Password field creates a password input and is usually created inside a form. Because it creates a password
 * field, when the user enters text it will show up as stars. Aside from that, the password field is just a normal text
 * field. Here's an example of how to use it in a form:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 title: 'Register',
 *                 items: [
 *                     {
 *                         xtype: 'emailfield',
 *                         label: 'Email',
 *                         name: 'email'
 *                     },
 *                     {
 *                         xtype: 'passwordfield',
 *                         label: 'Password',
 *                         name: 'password'
 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * Or on its own, outside of a form:
 *
 *     Ext.create('Ext.field.Password', {
 *         label: 'Password',
 *         value: 'existingPassword'
 *     });
 *
 * Because the password field inherits from {@link Ext.field.Text textfield} it gains all of the functionality that text
 * fields provide, including getting and setting the value at runtime, validations and various events that are fired as
 * the user interacts with the component. Check out the {@link Ext.field.Text} docs to see the additional functionality
 * available.

 * The radio field is an enhanced version of the native browser radio controls and is a good way of allowing your user
 * to choose one option out of a selection of several (for example, choosing a favorite color):

 *     var form = Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [

 *                 value: 'red',
 *                 label: 'Red',
 *                 checked: true
 *             },
 *             {
 *                 xtype: 'radiofield',
 *                 name : 'color',
 *                 value: 'green',
 *                 label: 'Green'
 *             },

 *                 label: 'Blue'
 *             }
 *         ]
 *     });
 *
 * Above we created a simple form which allows the user to pick a color from the options red, green and blue. Because
 * we gave each of the fields above the same {@link #name}, the radio field ensures that only one of them can be
 * checked at a time. When we come to get the values out of the form again or submit it to the server, only 1 value
 * will be sent for each group of radio fields with the same name:
 *
 *     form.getValues(); //looks like {color: 'red'}
 *     form.submit(); //sends a single field back to the server (in this case color: red)

 * The Search field creates an HTML5 search input and is usually created inside a form. Because it creates an HTML
 * search input type, the visual styling of this input is slightly different to normal text input controls (the corners
 * are rounded), though the virtual keyboard displayed by the operating system is the standard keyboard control.
 *
 * As with all other form fields in Sencha Touch, the search field gains a "clear" button that appears whenever there
 * is text entered into the form, and which removes that text when tapped.

/**
 * @aside guide forms
 *
 * The slider is a way to allow the user to select a value from a given numerical range. You might use it for choosing
 * a percentage, combine two of them to get min and max values, or use three of them to specify the hex values for a
 * color. Each slider contains a single 'thumb' that can be dragged along the slider's length to change the value.
 * Sliders are equally useful inside {@link Ext.form.Panel forms} and standalone. Here's how to quickly create a
 * slider in form, in this case enabling a user to choose a percentage:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'sliderfield',
 *                 label: 'Percentage',
 *                 value: 50,
 *                 minValue: 0,
 *                 maxValue: 100
 *             }
 *         ]
 *     });
 *
 * In this case we set a starting value of 50%, and defined the min and max values to be 0 and 100 respectively, giving
 * us a percentage slider. Because this is such a common use case, the defaults for {@link #minValue} and
 * {@link #maxValue} are already set to 0 and 100 so in the example above they could be removed.
 *
 * It's often useful to render sliders outside the context of a form panel too. In this example we create a slider that
 * allows a user to choose the waist measurement of a pair of jeans. Let's say the online store we're making this for
 * sells jeans with waist sizes from 24 inches to 60 inches in 2 inch increments - here's how we might achieve that:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'sliderfield',
 *                 label: 'Waist Measurement',
 *                 minValue: 24,
 *                 maxValue: 60,
 *                 increment: 2,
 *                 value: 32
 *             }
 *         ]
 *     });
 *
 * Now that we've got our slider, we can ask it what value it currently has and listen to events that it fires. For
 * example, if we wanted our app to show different images for different sizes, we can listen to the {@link #change}
 * event to be informed whenever the slider is moved:
 *
 *     slider.on('change', function(field, newValue) {
 *         if (newValue[0] > 40) {
 *             imgComponent.setSrc('large.png');
 *         } else {
 *             imgComponent.setSrc('small.png');
 *         }
 *     }, this);
 *
 * Here we listened to the {@link #change} event on the slider and updated the background image of an
 * {@link Ext.Img image component} based on what size the user selected. Of course, you can use any logic inside your
 * event listener.

/**
 * @aside guide forms
 *
 * The Url field creates an HTML5 url input and is usually created inside a form. Because it creates an HTML url input
 * field, most browsers will show a specialized virtual keyboard for web address input. Aside from that, the url field
 * is just a normal text field. Here's an example of how to use it in a form:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 title: 'Add Bookmark',
 *                 items: [
 *                     {
 *                         xtype: 'urlfield',
 *                         label: 'Url',
 *                         name: 'url'
 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * Or on its own, outside of a form:
 *
 *     Ext.create('Ext.field.Url', {
 *         label: 'Web address',
 *         value: 'http://sencha.com'
 *     });
 *
 * Because url field inherits from {@link Ext.field.Text textfield} it gains all of the functionality that text fields
 * provide, including getting and setting the value at runtime, validations and various events that are fired as the
 * user interacts with the component. Check out the {@link Ext.field.Text} docs to see the additional functionality
 * available.

 * A FieldSet is a great way to visually separate elements of a form. It's normally used when you have a form with
 * fields that can be divided into groups - for example a customer's billing details in one fieldset and their shipping
 * address in another. A fieldset can be used inside a form or on its own elsewhere in your app. Fieldsets can
 * optionally have a title at the top and instructions at the bottom. Here's how we might create a FieldSet inside a
 * form:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 title: 'About You',
 *                 instructions: 'Tell us all about yourself',
 *                 items: [
 *                     {
 *                         xtype: 'textfield',
 *                         name : 'firstName',
 *                         label: 'First Name'
 *                     },
 *                     {
 *                         xtype: 'textfield',
 *                         name : 'lastName',
 *                         label: 'Last Name'
 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * Above we created a {@link Ext.form.Panel form} with a fieldset that contains two text fields. In this case, all
 * of the form fields are in the same fieldset, but for longer forms we may choose to use multiple fieldsets. We also
 * configured a {@link #title} and {@link #instructions} to give the user more information on filling out the form if
 * required.

/**
 * The Form panel presents a set of form fields and provides convenient ways to load and save data. Usually a form
 * panel just contains the set of fields you want to display, ordered inside the items configuration like this:
 *
 *     @example
 *     var form = Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'textfield',
 *                 name: 'name',
 *                 label: 'Name'
 *             },
 *             {
 *                 xtype: 'emailfield',
 *                 name: 'email',
 *                 label: 'Email'
 *             },
 *             {
 *                 xtype: 'passwordfield',
 *                 name: 'password',
 *                 label: 'Password'
 *             }
 *         ]
 *     });
 *
 * Here we just created a simple form panel which could be used as a registration form to sign up to your service. We
 * added a plain {@link Ext.field.Text text field} for the user's Name, an {@link Ext.field.Email email field} and
 * finally a {@link Ext.field.Password password field}. In each case we provided a {@link Ext.field.Field#name name}
 * config on the field so that we can identify it later on when we load and save data on the form.
 *
 * ##Loading data
 *
 * Using the form we created above, we can load data into it in a few different ways, the easiest is to use
 * {@link #setValues}:
 *
 *     form.setValues({
 *         name: 'Ed',
 *         email: 'ed@sencha.com',
 *         password: 'secret'
 *     });
 *
 * It's also easy to load {@link Ext.data.Model Model} instances into a form - let's say we have a User model and want
 * to load a particular instance into our form:
 *
 *     Ext.define('MyApp.model.User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['name', 'email', 'password']
 *         }
 *     });
 *
 *     var ed = Ext.create('MyApp.model.User', {
 *         name: 'Ed',
 *         email: 'ed@sencha.com',
 *         password: 'secret'
 *     });
 *
 *     form.setRecord(ed);
 *
 * ##Retrieving form data
 *
 * Getting data out of the form panel is simple and is usually achieve via the {@link #getValues} method:
 *
 *     var values = form.getValues();
 *
 *     //values now looks like this:
 *     {
 *         name: 'Ed',
 *         email: 'ed@sencha.com',
 *         password: 'secret'
 *     }
 *
 * It's also possible to listen to the change events on individual fields to get more timely notification of changes
 * that the user is making. Here we expand on the example above with the User model, updating the model as soon as
 * any of the fields are changed:
 *
 *     var form = Ext.create('Ext.form.Panel', {
 *         listeners: {
 *             '> field': {
 *                 change: function(field, newValue, oldValue) {
 *                     ed.set(field.getName(), newValue);
 *                 }
 *             }
 *         },
 *         items: [
 *             {
 *                 xtype: 'textfield',
 *                 name: 'name',
 *                 label: 'Name'
 *             },
 *             {
 *                 xtype: 'emailfield',
 *                 name: 'email',
 *                 label: 'Email'
 *             },
 *             {
 *                 xtype: 'passwordfield',
 *                 name: 'password',
 *                 label: 'Password'
 *             }
 *         ]
 *     });
 *
 * The above used a new capability of Sencha Touch 2.0, which enables you to specify listeners on child components of any
 * container. In this case, we attached a listener to the {@link Ext.field.Text#change change} event of each form
 * field that is a direct child of the form panel. Our listener gets the name of the field that fired the change event,
 * and updates our {@link Ext.data.Model Model} instance with the new value. For example, changing the email field
 * in the form will update the Model's email field.
 *
 * ##Submitting forms
 *
 * There are a few ways to submit form data. In our example above we have a Model instance that we have updated, giving
 * us the option to use the Model's {@link Ext.data.Model#save save} method to persist the changes back to our server,
 * without using a traditional form submission. Alternatively, we can send a normal browser form submit using the
 * {@link #method} method:
 *
 *     form.submit({
 *         url: 'url/to/submit/to',
 *         method: 'POST',
 *         success: function() {
 *             alert('form submitted successfully!');
 *         }
 *     });
 *
 * In this case we provided the `url` to submit the form to inside the submit call - alternatively you can just set the
 * {@link #url} configuration when you create the form. We can specify other parameters (see {@link #method} for a
 * full list), including callback functions for success and failure, which are called depending on whether or not the
 * form submission was successful. These functions are usually used to take some action in your app after your data
 * has been saved to the server side.

 *
 * NavigationView is basically a {@link Ext.Container} with a {@link Ext.layout.Card card} layout, so only one view
 * can be visible at a time. However, NavigationView also adds extra functionality on top of this to allow
 * you to `push` and `pop` views at any time. When you do this, your NavigationView will automatically animate
 * between your current active view, and the new view you want to `push`, or the previous view you want to `pop`.
 *
 * Using the NavigationView is very simple. Here is a basic example of it in action:
 *
 *     @example
 *     var view = Ext.create('Ext.NavigationView', {
 *         fullscreen: true,
 *
 *         items: [{
 *             title: 'First',
 *             items: [{
 *                 xtype: 'button',
 *                 text: 'Push a new view!',
 *                 handler: function() {
 *                     // use the push() method to push another view. It works much like
 *                     // add() or setActiveItem(). it accepts a view instance, or you can give it
 *                     // a view config.
 *                     view.push({
 *                         title: 'Second',
 *                         html: 'Second view!'
 *                     });
 *                 }
 *             }]
 *         }]
 *     });
 *
 * Now, here comes the fun part: you can push any view/item into the NavigationView, at any time, and it will
 * automatically handle the animations between the two views, including adding a back button (if necessary)
 * and showing the new title.
 *
 *     view.push({
 *         title: 'A new view',
 *         html: 'Some new content'
 *     });
 *
 * As you can see, it is as simple as calling the {@link #method-push} method, with a new view (instance or object). Done.
 *
 * You can also `pop` a view at any time. This will remove the top-most view from the NavigationView, and animate back
 * to the previous view. You can do this using the {@link #method-pop} method (which requires no arguments).
 *
 *     view.pop();

 *
 * Tab Panels are a great way to allow the user to switch between several pages that are all full screen. Each
 * Component in the Tab Panel gets its own Tab, which shows the Component when tapped on. Tabs can be positioned at
 * the top or the bottom of the Tab Panel, and can optionally accept title and icon configurations.
 *
 * Here's how we can set up a simple Tab Panel with tabs at the bottom. Use the controls at the top left of the example
 * to toggle between code mode and live preview mode (you can also edit the code and see your changes in the live
 * preview):
 *
 *     @example miniphone preview
 *     Ext.create('Ext.TabPanel', {
 *         fullscreen: true,
 *         tabBarPosition: 'bottom',
 *
 *         defaults: {
 *             styleHtmlContent: true
 *         },
 *
 *         items: [
 *             {
 *                 title: 'Home',
 *                 iconCls: 'home',
 *                 html: 'Home Screen'
 *             },
 *             {
 *                 title: 'Contact',
 *                 iconCls: 'user',
 *                 html: 'Contact Screen'
 *             }
 *         ]
 *     });
 * One tab was created for each of the {@link Ext.Panel panels} defined in the items array. Each tab automatically uses
 * the title and icon defined on the item configuration, and switches to that item when tapped on. We can also position
 * the tab bar at the top, which makes our Tab Panel look like this:
 *
 *     @example miniphone preview
 *     Ext.create('Ext.TabPanel', {
 *         fullscreen: true,
 *
 *         defaults: {
 *             styleHtmlContent: true
 *         },
 *
 *         items: [
 *             {
 *                 title: 'Home',
 *                 html: 'Home Screen'
 *             },
 *             {
 *                 title: 'Contact',
 *                 html: 'Contact Screen'
 *             }
 *         ]

    This file creates a global JSON object containing two methods: stringify
    and parse.

        JSON.stringify(value, replacer, space)
            value       any JavaScript value, usually an object or array.

            replacer    an optional parameter that determines how object
                        values are stringified for objects. It can be a
                        function or an array of strings.

            space       an optional parameter that specifies the indentation
                        of nested structures. If it is omitted, the text will
                        be packed without extra whitespace. If it is a number,
                        it will specify the number of spaces to indent at each
                        level. If it is a string (such as '\t' or '&nbsp;'),
                        it contains the characters used to indent at each level.

            This method produces a JSON text from a JavaScript value.

            When an object value is found, if the object contains a toJSON
            method, its toJSON method will be called and the result will be
            stringified. A toJSON method does not serialize: it returns the
            value represented by the name/value pair that should be serialized,
            or undefined if nothing should be serialized. The toJSON method
            will be passed the key associated with the value, and this will be
            bound to the value

            For example, this would serialize Dates as ISO strings.

                Date.prototype.toJSON = function (key) {
                    function f(n) {
                        // Format integers to have at least two digits.
                        return n < 10 ? '0' + n : n;
                    }

                    return this.getUTCFullYear()   + '-' +
                         f(this.getUTCMonth() + 1) + '-' +
                         f(this.getUTCDate())      + 'T' +
                         f(this.getUTCHours())     + ':' +
                         f(this.getUTCMinutes())   + ':' +
                         f(this.getUTCSeconds())   + 'Z';
                };

            You can provide an optional replacer method. It will be passed the
            key and value of each member, with this bound to the containing
            object. The value that is returned from your method will be
            serialized. If your method returns undefined, then the member will
            be excluded from the serialization.

            If the replacer parameter is an array of strings, then it will be
            used to select the members to be serialized. It filters the results
            such that only members with keys listed in the replacer array are
            stringified.

            Values that do not have JSON representations, such as undefined or
            functions, will not be serialized. Such values in objects will be
            dropped; in arrays they will be replaced with null. You can use
            a replacer function to replace those with JSON values.
            JSON.stringify(undefined) returns undefined.

            The optional space parameter produces a stringification of the
            value that is filled with line breaks and indentation to make it
            easier to read.

            If the space parameter is a non-empty string, then that string will
            be used for indentation. If the space parameter is a number, then
            the indentation will be that many spaces.

            Example:

            text = JSON.stringify(['e', {pluribus: 'unum'}]);
            // text is '["e",{"pluribus":"unum"}]'


            text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
            // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'

            text = JSON.stringify([new Date()], function (key, value) {
                return this[key] instanceof Date ?
                    'Date(' + this[key] + ')' : value;
            });
            // text is '["Date(---current time---)"]'


        JSON.parse(text, reviver)
            This method parses a JSON text to produce an object or array.
            It can throw a SyntaxError exception.

            The optional reviver parameter is a function that can filter and
            transform the results. It receives each of the keys and values,
            and its return value is used instead of the original value.
            If it returns what it received, then the structure is not modified.
            If it returns undefined then the member is deleted.

            Example:

            // Parse the text. Values that look like ISO date strings will
            // be converted to Date objects.

            myData = JSON.parse(text, function (key, value) {
                var a;
                if (typeof value === 'string') {
                    a =
/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
                    if (a) {
                        return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
                            +a[5], +a[6]));
                    }
                }
                return value;
            });

            myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
                var d;
                if (typeof value === 'string' &&
                        value.slice(0, 5) === 'Date(' &&
                        value.slice(-1) === ')') {
                    d = new Date(value.slice(5, -1));
                    if (d) {
                        return d;
                    }

// Docs for the singleton instance created by above factory:

/**
 * @class Ext.Viewport
 * @extends Ext.viewport.Default
 * @singleton
 *
 * Ext.Viewport is a instance created when you use {@link Ext#setup}. Because {@link Ext.Viewport} extends from
 * {@link Ext.Container}, it has as {@link #layout} (which defaults to {@link Ext.layout.Card}). This means you
 * can add items to it at any time, from anywhere in your code. The {@link Ext.Viewport} {@link #cfg-fullscreen}
 * configuration is `true` by default, so it will take up your whole screen.
 *
 *     @example raw
 *     Ext.setup({
 *         onReady: function() {
 *             Ext.Viewport.add({
 *                 xtype: 'container',
 *                 html: 'My new container!'
 *             });
 *         }
 *     });
 *
 * If you want to customize anything about this {@link Ext.Viewport} instance, you can do so by adding a property
 * called `viewport` into your {@link Ext#setup} object:
 *
 *     @example raw
 *     Ext.setup({
 *         viewport: {
 *             layout: 'vbox'
 *         },
 *         onReady: function() {
 *             //do something
 *         }
 *     });
 *
 * **Note** if you use {@link Ext#onReady}, this instance of {@link Ext.Viewport} will **not** be created. Though, in most cases,
 * you should **not** use {@link Ext#onReady}.
