Add GPIO.setmode #54

Seems to me that we want to use GPIO.BOARD, but you used GPIO.BCM in some of your code. I'm not clear on what each does, though.

GPIO.BCM matches the numbers printed on the Raspberry Pi cobbler we use and in Fritzing.

I think the upside of GPIO.BOARD is that it will work across Raspberry Pi versions, but I'd rather sacrifice that to eliminate the confusion of having to keep looking at this diagram to map the board numbers to the board-independent numbers.
