System.Random.Mersenne.Pure64.Base

Tested with: GHC 6.8.2

A purely functional binding 64 bit binding to the classic mersenne twister random number generator. This is more flexible than the impure 'mersenne-random' library, at the cost of being much slower. This generator is however, many times faster than System.Random, and yields high quality randoms with a long period.
