Hacked together collision detection system using spacial hashing. First profiling results look v promising.
Fixed bug causing collisions to not work at all.
Made zones a field on circleHitbox to avoid constant memory allocation. Made a huge difference to speed\!
Pre-allocate memmory for the bounding box slice on each hitbox.
Added a bunch of comments.
Fixed a bug where sometimes collisions would get counted more than once. Should add a reg test for this.
