/**
* 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 Deprecated since version 2.3, use CakeResponse::file() instead
