 AABB Overlap
--------------

This requires each table passed into this function to have values for the following;
	x - current x position
	y - current y position
	h - object height
	w - object width

AABB collisions work best with purely rectangular objects.
For more advanced collision methods, check our demoman.net forsome excellent tutorials on the subject.


function aabbOverlap(a,b)
	return ((a.x+a.w > b.x)
					and (a.x < b.x+b.w))
		and ((a.y+a.h > b.y)
					and (a.y < b.y+b.h))
end
