+// ==========================================================================================

+

+// this program is a JavaScript version of Mersenne Twister, with concealment and encapsulation in class,

+// an almost straight conversion from the original program, mt19937ar.c,

+// translated by y. okada on July 17, 2006.

+// Changes by Jesse Ruderman: added "var" keyword in a few spots; added export_mta etc; pasted into fuzz.js.

+// in this program, procedure descriptions and comments of original source code were not removed.

+// lines commented with //c// were originally descriptions of c procedure. and a few following lines are appropriate JavaScript descriptions.

+// lines commented with /* and */ are original comments.

+// lines commented with // are additional comments in this JavaScript version.

+// before using this version, create at least one instance of MersenneTwister19937 class, and initialize the each state, given below in c comments, of all the instances.

+/*

+   A C-program for MT19937, with initialization improved 2002/1/26.

+   Coded by Takuji Nishimura and Makoto Matsumoto.

+

+   Before using, initialize the state by using init_genrand(seed)

+   or init_by_array(init_key, key_length).
