got text to be able to draw on screen
ff_draw draws a red 'a' in the middle of the screen...
ff_draw puts zeroes at every block in the maze
this is ready for application!
VirtualRobot has a ff_map, sends to draw_ff
draw_ff now prints the values of ff_map where it should go
fixed flood fill computation
it turns out that you do need 4 forloops for each direction but the point is that it works.  Since the maze is only 16x16 it can't be too slow to actually compute but this would not be good for large mazes
added a //gettters// section to make it easier to read
VirtualRobot now computes the flood fill
it computes the flood fill using the MazeMap from the VirtualMaze object passed to the constructor
Merge branch 'visual_ff'
flood fill algorithm has been fixed and now displays on the virtal maze.  We are getting closer!
