Mersenne Twister 19937 generator
mt19937 is A Mersenne Twister pseudo-random generator of 32-bit numbers with a state size of 19937 bits.
See http://beam.acclab.helsinki.fi/~knordlun/mc/mt19937.c for detail implement information.
The following is the C source code declation:
/* A C-program for MT19937: Real number version / / genrand() generates one pseudorandom real number (double) / / which is uniformly distributed on [0,1]-interval, for each / / call. sgenrand(seed) set initial values to the working area / / of 624 words. Before genrand(), sgenrand(seed) must be / / called once. (seed is any 32-bit integer except for 0). / / Integer generator is obtained by modifying two lines. / / Coded by Takuji Nishimura, considering the suggestions by / / Topher Cooper and Marc Rieffel in July-Aug. 1997. */

npm install mt19937
The default seed is 4357, Call Srand() set the seed if you need before Fetch any Number.
