/**
 * 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.
