lacking most features, but! im doing pretty good so far.  code has NOT been cleaned, so lots of useless characters/repetition... and like i said, many features are missing, so there are placeholders for testing (setWidth, numberOfMines, etc.)
i've run into a slight major problem .  how would i go about automatically clearing empty mine squares after one (empty one) has been clicked?  i can make it clear the ones adjacent, but i need it to clear in all directions as far as possible... any ideas?  i assume i'll need some sort of an 'until' function...?
btw if you wanted to see it   border images unfinished.  pretty snazzy for tk.

#TERMINATED HERE
so even with the reorganized code (which is much faster), i'm still not getting it to work.  i know its going to do lots of calculations, but good lands, there's only 100 possible squares (in this setup).
and even in 100, it still go in circles forever unless i tell it not to check what has already been checked.  probably the problem...
any ideas?
