/* This is designed for 16-bit undilated integers and 32-bit dilated
 * integers.  If we want to scale that up, it's an easy change but you will
 * need to make it. - Greg 00/05/12
 */

/* Rewrote by Jiahu Deng  06/08/2005
   modified the undilated-lookup table, use the algorithms from 
   Prof.Wise's paper, Converting to and from Dilated Integers.
   Added supports for anti-dilated integers.
