Removed use of arrows in project, cleaned up code

- Figuring out how to lay out arrows was unnecessarily difficult, and ended up being too distracting,
so utilizing the column space each node and its children are in was a much cleaner way to represent a
subtree relationship
- Figure will closely resemble a treemap
