  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.

  Before using, initialize the state by using init_genrand(seed)
  or init_by_array(init_key, key_length).
