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