"""
A simple Model-View-Controller framework for separating
presentation, business logic, and data.

A google search reveals several interesting pages to refer
to while designing this implementation:

http://www.object-arts.com/EducationCentre/Overviews/MVC.htm

Model-View-Presenter is a slightly newer concept developed by IBM
in the early-mid nineties and now used extensively in Dolphin SmallTalk:

Pretty pictures, for sure. I'll try to keep this implementation simple
while trying to learn as much as possible from previous implementations.

This module creates many circular references. It is therefore recommended
that subclasses do not implement a __del__ method.
