definition module Random
/**
* This module provides a pseudo random generator based
* on the Mersenne Twister algorithm

* Version 1.0.1 - July 30, 1999 - Thorsten Zoerner
* Catholic University of Nijmegen - zoerner@cs.kun.nl
*
* This implementation is a rewrite of a C program by T. Nishimura
* which can be found in the paper "Mersenne Twister: A 
* 623-dimensionally equidistributed uniform pseudorandom number 
* generator" by M. Matsumoto and T. Nishimura in ACM Transactions 
* on Modeling and Computer Simulation, vol. 8, no. 1, 
* January 1998, pp. 3-30.
