/*- THE DEAL:
* Suppose that for each value of query strings 'c' (controller - the class)
* and 'a' (action - the method), we want to call the action of the
* controller class. Example: for the address http://site/?c=Home&a=index
* the action "index" of the controller "Home" will be processed if *possible*.
*
* Here is a way to do the work using the Func class.
