synopsis:        Generate high quality pseudorandom numbers purely using a Mersenne Twister
description:
    The Mersenne twister is a pseudorandom number generator developed by
    Makoto Matsumoto and Takuji Nishimura that is based on a matrix linear
    recurrence over a finite binary field. It provides for fast generation
    of very high quality pseudorandom numbers. The source for the C code
    can be found here:

    <http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/emt64.html>
    .
    This library provides a purely functional binding to the 64 bit
    classic mersenne twister, along with instances of RandomGen, so the
    generator can be used with System.Random. The generator should
    typically be a few times faster than the default StdGen (but a tad
    slower than the impure 'mersenne-random' library based on SIMD
    instructions and destructive state updates.
