Summary: Fast Splittable PRNG

Description: 

Pure Haskell implementation of SplitMix described in

Guy L. Steele, Jr., Doug Lea, and Christine H. Flood. 2014. Fast splittable
pseudorandom number generators. In Proceedings of the 2014 ACM
International Conference on Object Oriented Programming Systems Languages &
Applications (OOPSLA '14). ACM, New York, NY, USA, 453-472. DOI:
<https://doi.org/10.1145/2660193.2660195>

The paper describes a new algorithm /SplitMix/ for /splittable/
pseudorandom number generator that is quite fast: 9 64 bit
arithmetic/logical operations per 64 bits generated.

/SplitMix/ is tested with two standard statistical test suites (DieHarder
and TestU01, this implementation only using the former) and it appears to
be adequate for "everyday" use, such as Monte Carlo algorithms and
randomized data structures where speed is important.

In particular, it __should not be used for cryptographic or security
applications__, because generated sequences of pseudorandom values are too
predictable (the mixing functions are easily inverted, and two successive
outputs suffice to reconstruct the internal state).
