This repo is for prng impelementations. The one in the std lib is pretty good, but for fast simulations others may be more appropriate.
As of now, there is only one prng here: the xoroshiro+128
prng. Very fast. It needs two uint64s to seed it, and
I just use the normal Go math/rand prng to do so:
rand.Seed(time.Now().Unix())
xrnd := xoroshiro.New(rand.Uint64(), rand.Uint64())
