class
KeccakFastRngKeccakFastRng - A KeccakF1600 based fast pseudo-random number generator. This class tunes the KeccakF1600 algorithm for best performance in pseudo random number generation. Performance is improved while still retaining quality random number generation, according to the findings in seciton "4.1.1 Statistical tests" from http:/
