entity.rs needs a refactor. The branching on the right and the left is no bueno. Some alternatives:
Keep the node structure but make a function do the stuff that's duplicated. Thread-spawn it (bench this) on big recursive calls and do both sides at once.
Change left, right to [Node; 2]
Node could be an enum of leaf or internal, getting rid of some options
The tree should be an iter so we don't have to process the entire vec beforehand
There might be better (unsafe?) ways to represent the tree in memory...maybe.
