/**
* 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.
*
