You are welcome Armen.  The project is the sum of the contributions of lot of 
people: code or advices.

Great. You are welcome.

IMHO, in the MVC pattern any Controller have:

 * An interface or "entry point".
 * A call to the View to show the information, "page builder".
 * A business logic.

We can keep all that in the same directory or organized in one directory for 
each concept.  At the end it would be the same code working in the same way!

I prefer have it separated but it is just my current personal opinion. I can 
be mistaken.
