This is Swift port of pseudorandom number generator
wyrand from wyhash by Wang Yi. On 64-bit hardware, it is should be effectively faster than any other commonly available random number generator. It meets quality standards: it passes Big Crunch.
It conforms to RandomNumberGenerator protocol.
var gen = WyRand(seed: 42) gen.next() // generates a 64-bit random number (1...10).shuffled(using: &gen)
