Initial code for GUI.  OpenGL crashing is expected.
Initial menu code, nothing working yet.
Callbacks for buttons on right side added, still some crashing issues.
Map now regenerates without crashing.  OpenGL code commented out until context working.
Readded SDL to render map (fltk still handles UI).  OpenGL code readded.
Behaviours now update when update button on GUI is pushed.
Fixed bug where first node always chosen if total probability is 0.
Stopped rendering edges for TSP type maps.
