Detailed Description

This is the Model abstract class of Model_View_Control design pattern.

It handles change_flag, a semaphore used to indicate that a redraw is required for all attached widgets.

The controller or any other entities that modify the model must set the change_flag and the widget in charge of its screen representation must clear the change_flag
