// Created by Brad Hefta-Gaub on 11/1/14.

//
// This is an example of an entity script which when assigned to a non-model entity like a box or sphere, will
// change the color of the entity when you hover over it. This script uses the JavaScript prototype/class functionality
// to construct an object that has methods for hoverEnterEntity and hoverLeaveEntity;
