GUI is now loading up mazes from application that Erin created.
Listeners created for every button.
Game functions as expected. Can reset and move to next maze. Fixed a bug
in reset. There is a problem with Breadth first search
Added a move counter.
Did an overhaul of the maze gui. It looks a lot more like the one used
by the developers of the iPhone version. It was more conveinent and it
matches the tutorial now. Aspect ratios of images work for most devices
(excluding tablets).
