24  A C-program for MT19937, with initialization improved 2002/2/10.
25  Coded by Takuji Nishimura and Makoto Matsumoto.
26  This is a faster version by taking Shawn Cokus's optimization,
27  Matthe Bellew's simplification, Isaku Wada's real version.
28  David Bateman added normal and exponential distributions following
29  Marsaglia and Tang's Ziggurat algorithm.
