You might need this class as well, it isn't implemented, but I think the Element class has some calls to it, so better safe than sorry:

## Created By: George Lecakes
## Purpose: 
##		The Visualizer class is meant as a container
##		to hold the model information as well as what
##		to do when the user selected an object.
##
##	Requirements:
##		This class requires a timer to check
##		for onMouseOver events. 
##
## Date Created: August 13, 2007
##		Created the class.
