void OEGetBitCounts(const OEBitVector& a, const OEBitVector& b,
                    unsigned int *onlyA, unsigned int *onlyB,
                    unsigned int *bothAB, unsigned int *neitherAB)

Count the number of bits when comparing the two OEBitVector arguments a and b. This function is optimized so that the bitvectors only need to be traversed once.

The counts are returned as the following arguments with the corresponding values.

*onlyA     =   a  & ~b;
*onlyB     =  ~a  &  b;
*bothAB    =   a  &  b;
*neitherAB = ~(a  &  b);
