The run_player script now creates the include file for the floorplan, so that the floorplan can be specified from a command line arg.
Added simple file extension check to run_player.py to help prevent overwriting a file if the command syntax is incorrect.
Basic a_star implementation. Just need to integrate it with the controller now.
imp_pot_controller should use a_star (actually... should be a new controller...). Right now just having trouble drawing a grid (since coords are relative to the robot, and are thus not global).
