/**
* Represents an Ext JS 4 application, which is typically a single page app using a {@link Ext.container.Viewport Viewport}.
* A typical Ext.app.Application might look like this:
*
* Ext.application({
* name: 'MyApp',
* launch: function() {
* Ext.create('Ext.container.Viewport', {
* items: {
* html: 'My App'
* }
* });
* }
* });
*
* This does several things. First it creates a global variable called 'MyApp' - all of your Application's classes (such
* as its Models, Views and Controllers) will reside under this single namespace, which drastically lowers the chances
* of colliding global variables. The MyApp global will also have a getApplication method to get a reference to
* the current application:
*
* var app = MyApp.getApplication();
*
* When the page is ready and all of your JavaScript has loaded, your Application's {@link #launch} function is called,
* at which time you can run the code that starts your app. Usually this consists of creating a Viewport, as we do in
* the example above.
*
* # Telling Application about the rest of the app
*
* Because an Ext.app.Application represents an entire app, we should tell it about the other parts of the app - namely
* the Models, Views and Controllers that are bundled with the application. Let's say we have a blog management app; we
* might have Models and Controllers for Posts and Comments, and Views for listing, adding and editing Posts and Comments.
* Here's how we'd tell our Application about all these things:
*
* Ext.application({
* name: 'Blog',
* models: ['Post', 'Comment'],
* controllers: ['Posts', 'Comments'],
*
* launch: function() {
* ...
* }
* });
*
* Note that we didn't actually list the Views directly in the Application itself. This is because Views are managed by
* Controllers, so it makes sense to keep those dependencies there. The Application will load each of the specified
* Controllers using the pathing conventions laid out in the [application architecture guide][mvc] - in this case
* expecting the controllers to reside in app/controller/Posts.js and app/controller/Comments.js. In turn, each
* Controller simply needs to list the Views it uses and they will be automatically loaded. Here's how our Posts
* controller like be defined:
*
* Ext.define('MyApp.controller.Posts', {
* extend: 'Ext.app.Controller',
* views: ['posts.List', 'posts.Edit'],
*
* //the rest of the Controller here
* });
*
* Because we told our Application about our Models and Controllers, and our Controllers about their Views, Ext JS will
* automatically load all of our app files for us. This means we don't have to manually add script tags into our html
* files whenever we add a new class, but more importantly it enables us to create a minimized build of our entire
* application using Sencha Cmd.
*
* # Deriving from Ext.app.Application
*
* Typically, applications do not derive directly from Ext.app.Application. Rather, the
* configuration passed to `Ext.application` mimics what you might do in a derived class.
* In some cases, however, it can be desirable to share logic by using a derived class
* from `Ext.app.Application`.
*
* Derivation works as you would expect, but using the derived class should still be the
* job of the `Ext.application` method.
*
* Ext.define('MyApp.app.Application', {
* extend: 'Ext.app.Application',
* name: 'MyApp',
* ...
* });
*
* Ext.application('MyApp.app.Application');
*
* For more information about writing Ext JS 4 applications, please see the [application architecture guide][mvc].
