void right_justify	(	T *	data,
		unsigned int	num_samples,
		unsigned int	bitsToMove
	)

This function handles the case where the actual bits per pixel per band is less then the actual bpppb AND where the data is vcl_left justified.

This shifts the data so that it is right justified. As of now, this function is untests as I don't have any vcl_left justified data (the NITF spec discourages using it -- probably because it is such a PITA)
