BFS and DFS are fully functional now (except for points...i think i need
to implement some GUI stuff and the map properties file for those to
work the way i want). added uniform agent, too lazy to add greedy and A*
agents--might need my points working before that is fully functional.

next steps:
- add in greedy and A* agents
- add points?
- add GUI features?
- a2 functionality
