/**
 * Media View provides a custom view implementation for sending files to visitors. Its great
 * for making the response of a controller action be a file that is saved somewhere on the filesystem.
 *
 * An example use comes from the CakePHP internals. MediaView is used to serve plugin and theme assets,
 * as they are not normally accessible from an application's webroot. Unlike other views, MediaView
 * uses several viewVars that have special meaning:
 *
 * - `id` The filename on the server's filesystem, including extension.
 * - `name` The filename that will be sent to the user, specified without the extension.
 * - `download` Set to true to set a `Content-Disposition` header. This is ideal for file downloads.
 * - `path` The absolute path, including the trailing / on the server's filesystem to `id`.
 * - `mimeType` The mime type of the file if CakeResponse doesn't know about it.
 *      Must be an associative array with extension as key and mime type as value eg. array('ini' => 'text/plain')
 *
 * ### Usage
 *
 * ```
 * class ExampleController extends AppController {
 *              public function download() {
 *                      $this->viewClass = 'Media';
 *                      $params = array(
 *                              'id' => 'example.zip',
 *                              'name' => 'example',
 *                              'download' => true,
 *                              'extension' => 'zip',
 *                              'path' => APP . 'files' . DS
 *                      );
 *                      $this->set($params);
 *              }
 * }
 * ```
 *
 * @package       Cake.View
 * @deprecated 3.0.0 Deprecated since version 2.3, use CakeResponse::file() instead
