/**
* App is responsible for resource location, and path management.
*
* ### Adding paths
*
* Additional paths for Templates and Plugins are configured with Configure now. See config/app.php for an
* example. The `App.paths.plugins` and `App.paths.templates` variables are used to configure paths for plugins
* and templates respectively. All class based resources should be mapped using your application's autoloader.
*
* ### 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 get
* the path to a plugin's helpers you would call `App::path('View/Helper', 'MyPlugin')`
*
* ### Locating plugins
*
* Plugins can be located with App as well. Using Plugin::path('DebugKit') for example, will
* give you the full path to the DebugKit plugin.
