Uses QuadTree to speed up the method of finding collisions between objects. Each branch of the tree on average improves collision detection by a factor of 4 over bruit force for the objects within a branch. A two level tree, a performance improved by a factor of 16. A three level tree, improvement factor of 48. Etc.
