/**
 * Application controller class for organization of business logic.
 * Provides basic functionality, such as rendering views inside layouts,
 * automatic model availability, redirection, callbacks, and more.
 *
 * Controllers should provide a number of 'action' methods. These are public
 * methods on a controller that are not inherited from `Controller`.
 * Each action serves as an endpoint for performing a specific action on a
 * resource or collection of resources. For example adding or editing a new
 * object, or listing a set of objects.
 *
 * You can access request parameters, using `$this->getRequest()`. The request object
 * contains all the POST, GET and FILES that were part of the request.
 *
 * After performing the required action, controllers are responsible for
 * creating a response. This usually takes the form of a generated `View`, or
 * possibly a redirection to another URL. In either case `$this->getResponse()`
 * allows you to manipulate all aspects of the response.
 *
 * Controllers are created based on request parameters and
 * routing. By default controllers and actions use conventional names.
 * For example `/posts/index` maps to `PostsController::index()`. You can re-map
 * URLs using Router::connect() or RouteBuilder::connect().
 *
 * ### Life cycle callbacks
 *
 * CakePHP fires a number of life cycle callbacks during each request.
 * By implementing a method you can receive the related events. The available
 * callbacks are:
 *
 * - `beforeFilter(EventInterface $event)`
 *   Called before each action. This is a good place to do general logic that
 *   applies to all actions.
 * - `beforeRender(EventInterface $event)`
 *   Called before the view is rendered.
 * - `beforeRedirect(EventInterface $event, $url, Response $response)`
 *    Called before a redirect is done.
 * - `afterFilter(EventInterface $event)`
 *   Called after each action is complete and after the view is rendered.
