JS Timer troubles

gistfile1.coffee

# I have this timer setup.  It's the only way I could get it to work but seems very wrong...  
# Specifically in processUserCommand if I don't clearTimeout's every time the win and max 
# moves scenarios no longer work.  Without the timer tear down the app just goes on and on 
# after reaching max moves and/or win.

# Sample app up on http://solitr.herokuapp.com/klondike-turn-three-hints
