gen_fsm state machine drawing tool

[Vance Shipley]

I have cleaned up my drawing tool and incorporated several enhancements.
I have attached an example output graphic from dot for our T1 alarm state 
machine, as well as the dot output specification from graph_fsm and the 
graph_fsm.erl source file itself.  I hope someone finds it useful. :)

It won't likely work for every case of coding style but I make it work 
for the souerce files I create.  It gets enhanced to deal with more cases
as I need them internally.  If you have any comments, suggestions or
enhancement requests let me know.
