/**
* This class represents the random number generator.
* It uses the SIMD-oriented Fast Mersenne Twister code v1.4.1 from
* http://www.math.sci.hiroshima-u.ac.jp/~%20m-mat/MT/SFMT/index.html
* To use this RNG, the class needs a sfmt_t structure for the RNG's internal state.
* It has to be initialized by sfmt_init_gen_rand() which is done in the constructor.
* The function sfmt_genrand_uint64() can then be used to create a 64 bit unsigned int
* pseudorandom number. This is done in getNumber().
* For more information see the author's website and look at the documentation and
* examples that are part of the official downloads.
