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.
