splitmix

This random number generator is NOT suitable for cryptographic applications.

Implements the SplitMix algorithm from Fast Splittable Pseudorandom Number Generators by Steele, Lea, and Flood.

This provides a splittable random number generator.

Both a functional and a mutable interface are provided. The functional interface matches the node-lcg library. It should be drop-in compatible. The node-lcg is based on Distributed random number generation by Burton and Page. As far as I know, its statistical properties haven't been tested with DieHard or TestU01 unlike the SplitMix algorithm (but not this implementation). Being from 1992 and based on a linear congruential generator, it is not likely to perform well statistically.

It is tested to produce the same values as the Haskell SplitMix implementation.
