trying to move buttons, labels to right

grid() is making it difficult
trying to debug why I can't put the countLabel et al

where I want them.  It looks like the holes appear right under tk, but
the labels and buttons created in Puzzle are under a subframe
brought all the labels and buttons back with.grid

debugging the graphic items addresses,  holes are top level, but the
labels and buttons are down one...
split Board class into a separate file
Changed GameOver() to MovesLeft()
moving the labels and buttons that were in Puzzle.py to

Board.py fixes the position problems.  Commented out some debug code.
TO-DO: add help, alphabetize functions, add Congratulations?
