Cave Generator

I've created a small script that generates a cave using cellular automata. I might possibly add greedy meshing to this generator to reduce the part count by 2 - 3 times, but I'm not doing that for now. Later on I might create a new cave generator, but in 3D and use marching cubes to generate it. That would definitely make for a fun experience, but I'm not making that right now. Feel free to edit the game to see how all of it works.
