3 Controller and dispatcher

In VelocityWeb framework, controller is formed by following classes:

org.velocityweb.controller.ControllerServlet
org.velocityweb.controller.Controller
org.velocityweb.controller.DispatcherTreeManager

And in web application that uses VelocityWeb framework, need to write sub-class of following classes:

org.velocityweb.controller.ControllerServlet
org.velocityweb.controller.Controller

Normally, web applications using VelocityWeb will write sub-class of both ControllerServlet and Controller. There is no need to write sub-class for DispatcherTreeManager.

The reason that we seperate Controller class from ControllerServlet is that we don't want ControllerServlet to be too big. And, in future version, we want to use this Controller class in background batch job.
