Controller_Welcome
extends Controller
extends Kohana_Controller

Abstract controller class. Controllers should only be created using a Request.

Controllers methods will be automatically called in the following order by the request:

$controller = new Controller_Foo($request);
$controller->before();
$controller->action_bar();
$controller->after();

The controller action should add the output it creates to $this->response->body($output), typically in the form of a View, during the "action" part of execution.
