//Sample code for the game engine which makes a platformer where a little Booth figure can jump on platforms to get a coin.

Partial Mock Class: Booth

	public Booth(){
		super(new Image("Booth.png"));

    }
    
    //Probably have other stuff here too.

Partial Mock Class: BasicPhysics

Description of GameScene

GameScene will be the all encompassing mother class which HAS everything. It IS a scene so that anything that extends Application can set it as its Scene. This class will keep track of the master list of ALLLLLLLL the sprites (background, game, info, etc.) AND a master group of all of the Sprites' faces. The GameScene will also hold on to the main Timer (AnimationTimer?) and send off all of the Timer-related events (Collisions, Inputs, etc.). The GameScene also is the keeper of the current x,y position being shown at the bottom-left of the window the GameScene is part of.
