THIS IS NOT THE OFFICIAL CODE!!! THIS IS A PORT TO ROBOTC FOR VEX CORTEX - SEE BELOW

 Note:  I'd really hoped to have this more polished before release, but with the
		osPID coming out I felt that this needed to be out there NOW.  if you 
		encounter any issues please contact me, or post to the diy-pid-control
		google group.
 


 * Adapted for VEX ROBOTC by Brian Pratt <[email protected]>
 * Assumes that we're controlling rotation speed using a quad encoder
 * N.B. could be further simplified and warnings reduced (especially about doubles)
 * but I left a lot alone for ease of tracking any developments in the Arduino code
