/**

 * App is responsible for path management, class location and class loading.

 *

 * ### Adding paths

 *

 * You can add paths to the search indexes App uses to find classes using `App::build()`. Adding

 * additional controller paths for example would alter where CakePHP looks for controllers.

 * This allows you to split your application up across the filesystem.

 *

 * ### Packages

 *

 * CakePHP is organized around the idea of packages, each class belongs to a package or folder where other

 * classes reside. You can configure each package location in your application using `App::build('APackage/SubPackage', $paths)`

 * to inform the framework where should each class be loaded. Almost every class in the CakePHP framework can be swapped

 * by your own compatible implementation. If you wish to use you own class instead of the classes the framework provides,

 * just add the class to your libs folder mocking the directory location of where CakePHP expects to find it.

 *

 * For instance if you'd like to use your own HttpSocket class, put it under

 *

 *		app/Network/Http/HttpSocket.php

 *

 * ### Inspecting loaded paths

 *

 * You can inspect the currently loaded paths using `App::path('Controller')` for example to see loaded

 * controller paths.

 *

 * It is also possible to inspect paths for plugin classes, for instance, to see a plugin's helpers you would call

 * `App::path('View/Helper', 'MyPlugin')`

 *

 * ### Locating plugins and themes

 *

 * Plugins and Themes can be located with App as well. Using App::pluginPath('DebugKit') for example, will

 * give you the full path to the DebugKit plugin. App::themePath('purple'), would give the full path to the

 * `purple` theme.

 *

 * ### Inspecting known objects

 *

 * You can find out which objects App knows about using App::objects('Controller') for example to find

 * which application controllers App knows about.

 *
