-/** This class implements a powerful pseudo-random number generator
- * developed by Makoto Matsumoto and Takuji Nishimura during
- * 1996-1997.
- *
- * <b>Caveat:</b> It is recommended to use one of WELL generators rather
- * than the MersenneTwister generator (see
- * <a href="http://www.iro.umontreal.ca/~panneton/WELLRNG.html">
- * this paper</a> for more information).
- *
- * <p>This generator features an extremely long period
- * (2<sup>19937</sup>-1) and 623-dimensional equidistribution up to 32
- * bits accuracy. The home page for this generator is located at <a
- * href="http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/emt.html">
- * http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/emt.html</a>.</p>
-
- * <p>This generator is described in a paper by Makoto Matsumoto and
- * Takuji Nishimura in 1998: <a

- * Number Generator</a>, ACM Transactions on Modeling and Computer
- * Simulation, Vol. 8, No. 1, January 1998, pp 3--30</p>
-
- * <p>This class is mainly a Java port of the 2002-01-26 version of
- * the generator written in C by Makoto Matsumoto and Takuji
