This file contains the driver function for the third assignment of course CIV 2801 - Fundamentos de Computacao Grafica Aplicada - 2004.2. See documentation on class notes.
Each time the model or its image is manipulated on the screen, it is redisplayed to reflect the change.
The actions are currently set by the user through key commands. Part of the assignment is to add menus and/or buttons to perform the actions.
