Pure Haskell implementation of SplitMix, a splittable
 pseudorandom number generator that is quite fast.
 .
 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).
 .
 This package provides a library for the Haskell programming language.
