+   A C-program for MT19937-64 (2004/9/29 version).
+   Coded by Takuji Nishimura and Makoto Matsumoto.
+
+   This is a 64-bit version of Mersenne Twister pseudorandom number
+   generator.
+
+   Before using, initialize the state by using init_genrand64(seed)
+   or init_by_array64(init_key, key_length).
