** This is the algorithm that generates the error correction code (ECC) used to identify each IR-LED in

** This algorithm was *not* found in the binaries provided by Oculus (they only include pre-computed LUTs).

** The algorithm is pretty simple:
** All code words need to fulfil two requirements:
