+ *              First incorporated from the Mersenne Twister Random
+ *              Number Generator package. It was chosen because it is
+ *              in BSD-license and its performance is quite
+ *              reasonable. Of course if you look at the inventors's
+ *              page.  This random generator can actually gives
+ *              19937-bits period.  This is already far from we need. 
+ *              This will possibly good enough for the next 10 years. 
+ *
+ *              I also downgrade the code a little bit to avoid Sphinx's
