This program runs through one level of Pacman.  Be advised the game is not fully functional.  The ghost character was commented out due to the game freezing with multiple characters present.

srigdon3 1:b86030cf57c4 2 So far, this program will run through one level of what will hopefully be a full Pacman game.
srigdon3 1:b86030cf57c4 3 As of now, only Pacman will run all the way through, so the thread to start the blue ghost has
srigdon3 1:b86030cf57c4 4 been commented out. This program only runs through one level of the game.
