I have added the EventControllerContext that start to abstract the routing logic of the controller. The current implementation is still the same logic than before.

I have added the base class for controller responses:

/**
 * Must be used as base class for high level response provided by the controller that
 * will be translated into something at the portal level. The goal is to avoid to manipulate
 * the HTTP response directly.
 *
 * The test bed will of course use the HTTP response but the Presentation Framework will
 * work differently.
 *
 * So we really need to abstract everything done with the HttpServletResponse and *never* use
 * it in the controller.
 *
 * Typical usage should be :
 * ControllerResponse response = controller.invoker(ControllerRequest request);
 *
