/**
* Class constructor
*
* The request and response objects should be registered with the
* controller, as should be any additional optional arguments; these will be
* available via {@link getRequest()}, {@link getResponse()}, and
* {@link getInvokeArgs()}, respectively.
*
* When overriding the constructor, please consider this usage as a best
* practice and ensure that each is registered appropriately; the easiest
* way to do so is to simply call parent::__construct($request, $response,
* $invokeArgs).
*
* After the request, response, and invokeArgs are set, the
* {@link $_helper helper broker} is initialized.
*
* When the broker is instantiated immediately a contextswitch is added
* for defining the snippet context as the default context
*
* Finally, {@link init()} is called as the final action of
* instantiation, and may be safely overridden to perform initialization
* tasks; as a general rule, override {@link init()} instead of the
* constructor to customize an action controller's instantiation.
*
* @param Zend_Controller_Request_Abstract $request
* @param Zend_Controller_Response_Abstract $response
