Perl interface to the ISAAC PRNG Algorithm

Math::Random::ISAAC implements the ISAAC (Indirection, Shift, Accumulate, Add and Count) pseudorandom number generator (PRNG) algorithm described on the project page at: <URL:http://burtleburtle.net/bob/rand/isaac.html>

As with other algorithms like the Mersenne Twister (see Math::Random::MT), this algorithm is designed to take some seed information and produce seemingly random results as output.

The results are uniformly distributed, unbiased, and unpredictable unless you know the seed. The algorithm was published by Bob Jenkins in the late 1990s and despite the best efforts of many security researchers, no feasible attacks have been found to date.

For comparison with other algorithms intended to generate random data, the Mersenne Twister has a period of 2^19937-1, the related TT800 has a period of 2^800-1 values. ISAAC has a period of 2^8295 values on average.
