/**
 * This is a port of Shawn Cokus's implementation of the original Mersenne Twister algorithm (http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/MT2002/CODES/MTARCOK/mt19937ar-cok.c).
 * MT has a very high period of 2^19937. Though the authors of xorshift describe that a high period is not
 * very relevant (http://vigna.di.unimi.it/xorshift/). It is four times slower than xoroshiro128plus and
 * needs to recompute its state after generating 624 numbers.
 *
 * ```js
 * const gen = new Mt19937(new Date().getTime())
 * console.log(gen.next())
 * ```
