This time, we'll put together a generic "block" and make it easy to add them!

A few constraints:
	Size is fixed at 0.5 by 0.5 by 0.5
	We can land on the blocks
	We can walk onto blocks if they're not too high up
	Box locations will be in a vector, something we can communicate to the video card
	Boxes don't change location
		If they did, we would have to update video memory
	
Organization:
	Organization will be an increasingly large topic for us!
	For today:
		class Stone	
		class will contain a list of locations where there are stones
