/**
 * Controllers are the glue that binds an application together. That said, their main 
 * purpose is to listen for events (usually from views) and take some action. Here's how 
 * we might create a Controller to manage Users:
 *
 *      Ext.define('MyApp.controller.Users', {
 *          extend: 'Ext.app.Controller',
 *
 *          init: function() {
 *              console.log('Initialized Users! This happens before ' +
 *                          'the Application launch() function is called');
 *          }
 *      });
 *
 * The init function is a special method that is called when your application boots. It is 
 * called before the {@link Ext.app.Application Application}'s launch function is executed. 
 * This creates an area you can run code prior to Viewport creation.
 *
 * The controller's {@link #method-control} function
 * makes it easy to listen to events on your view classes and take some action with a 
 * handler function. Let's update our Users controller to tell us when the panel is 
 * rendered:
 *
 *      Ext.define('MyApp.controller.Users', {
 *          extend: 'Ext.app.Controller',
 *
 *          control: {
 *              'viewport > panel': {
 *                  render: 'onPanelRendered'
 *              }
 *          }
 *
 *          onPanelRendered: function() {
 *              console.log('The panel was rendered');
 *          }
 *      });
 *
 * The {@link Ext.app.BaseController#method-control control method} has now set up 
 * listeners on views in our application. The control method uses the ComponentQuery 
 * engine to quickly and easily get references to components on the page. If you are not 
 * familiar with ComponentQuery yet, be sure to check out the 
 * {@link Ext.ComponentQuery documentation}. In brief, it allows us to pass a 
 * CSS-like selector that will find every matching component on the page.
 *
 * In our init function above, we supplied 'viewport > panel', which translates to "find me 
 * every Panel that is a direct child of a Viewport". We then supplied an object that maps 
 * event names (just 'render' in this case) to handler functions. In short, whenever 
 * a component that matches our selector fires a 'render' event, our
 * onPanelRendered function is called.
 *
 * ## Event domains
 *
 * In Ext JS 4.2, we introduced the concept of event domains. In terms of MVC, an event 
 * domain is one or more base classes that fire events to which a Controller wants to 
 * listen. Besides Component event domain that encompass {@link Ext.Component}-descended 
 * Views, Controllers now can listen to events from data Stores, Ext Direct Providers, 
 * other Controllers, and Ext.GlobalEvents. This feature provides a way to communicate 
 * between parts of the whole application without the need to bind controllers together 
 * tightly, and allows to develop and test application parts in isolation.
 *
 * See usage examples in {@link #method-listen} method documentation.
 *
 * ## Using refs
 *
 * One of the most useful parts of Controllers is the ref system. These use 
 * {@link Ext.ComponentQuery} to make it really easy to get references to Views on your 
 * page. Let's look at an example of this now:
 *
 *      Ext.define('MyApp.controller.Users', {
 *          extend: 'Ext.app.Controller',
 *          
 *          refs: [{
 *              ref: 'list',
 *              selector: 'grid'
 *          }],
 *          
 *          control: {
 *              'button': {
 *                  click: 'refreshGrid'
 *              }
 *          },
 *          
 *          refreshGrid: function() {
 *              this.getList().store.load();
 *          }
 *      });
 *
 * This example assumes the existence of a {@link Ext.grid.Panel Grid} on the page, which 
 * contains a single button to refresh the Grid when clicked. In our refs array, we set up 
 * a reference to the grid. There are two parts to this - the 'selector', which is a 
 * {@link Ext.ComponentQuery ComponentQuery} selector which finds any grid on the page and
 * assigns it to the reference 'list'.
 *
 * By giving the reference a name, we get a number of things for free. The first is the 
 * getList function that we use in the refreshGrid method above. This is generated 
 * automatically by the Controller based on the name of our ref, which was capitalized and 
 * prepended with get to go from 'list' to 'getList'.
 *
 * The way this works is that the first time getList is called by your code, the 
 * ComponentQuery selector is run and the first component that matches the selector 
 * ('grid' in this case) will be returned. All future calls to getList will use a cached 
 * reference to that grid. Usually it is advised to use a specific ComponentQuery selector 
 * that will only match a single View in your application (in the case above our selector 
 * will match any grid on the page).
 *
 * Bringing it all together, we configure control
 * to listen to any click on a {@link Ext.button.Button button} and call our refreshGrid 
 * function (again, this will match any button on the page so we advise a more specific 
 * selector than just 'button', but have left it this way for simplicity). When the button 
 * is clicked we use out getList function to refresh the grid.
 *
 * You can create any number of refs and control any number of components this way, simply 
 * adding more functions to your Controller as you go. For an example of real-world usage 
 * of Controllers see the Feed Viewer example in the examples/app/feed-viewer folder in 
 * the SDK download.
 *
 * ## Generated getter methods
 *
 * Refs aren't the only thing that generate convenient getter methods. Controllers often 
 * have to deal with Models and Stores so the framework offers a couple of easy ways to 
 * get access to those too. Let's look at another example:
 *
 *      Ext.define('MyApp.controller.Users', {
 *          extend: 'Ext.app.Controller',
 *
 *          models: ['User'],
 *          stores: ['AllUsers', 'AdminUsers'],
 *
 *          init: function() {
 *              var User, allUsers, ed;
 *              
 *              User = this.getUserModel();
 *              allUsers = this.getAllUsersStore();
 *
 *              ed = new User({ name: 'Ed' });
 *              allUsers.add(ed);
 *          }
 *      });
 *
 * By specifying Models and Stores that the Controller cares about, it again dynamically 
 * loads them from the appropriate locations (app/model/User.js, app/store/AllUsers.js and 
 * app/store/AdminUsers.js in this case) and creates getter functions for them all. The 
 * example above will create a new User model instance and add it to the AllUsers Store.
 * Of course, you could do anything in this function but in this case we just did 
 * something simple to demonstrate the functionality.
