//ClassicSimulator - A class to simulate a classic minigolf ball in the quantum minigolf playing 
// fields. It needs two bitmaps, one containing the infinitely high part of the potential, 
// folded with the ball shape and a second with the finitely hard part of the potential. 
//
// The classic simulator is still heavy work in progress
