/**
 * App is responsible for path managment, 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 when you 
 * call App::import('Controller', 'Posts');  This allows you to split your application up across the filesystem.
 *
 * ### Inspecting loaded paths
 *
 * You can inspect the currently loaded paths using `App::path('controller')` for example to see loaded
 * controller paths.
 *
 * ### 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.
 *
