Re: printf bug - beware!

This isn't a bug either, but causes us and team 60 some amount of frustration over the weekend...

If any printf's are called before the Initialize_Serial_Coms() function is called in User Initialization, the RC will flip into a bizarre state: the disable light goes on and the program light flashes red and green. We could find no documentation on what the signal meant, and spent about 3 hours rebuilding our code before Jay noticed the errant printf at the top of User Initialization.

The problem seems pretty obvious in retrospect, but because of the obscurity of the RC feedback we were getting, I'd just like to warn other teams...don't make the same mistake =).
