 * NAME:        UT library math support
 *
 * COMMENTS:
 *      void UT_fastRandomSeed(int seed)
 *      Seed the fast random number generator
 *      
 *      fpreal UT_fastRandom(void)
 *      Really, really fast random number generation - pretty good
 *      distribution of sequential random numbers
 *
 *      Ref.  Numerical Recipes (pp 284)
 *
 *      Currently, only the fast random number generation is included
 *      here, however, in the future, there may be other utilities.
