Using a self-seeded RNG on wasm32-unknown-unknown

[golddranks]

Compile issue

Problem: There should be a way to use rand without system/environment dependencies.

Quick solution: Roll my own algorithm with multiplications, modulos and bitshifts. (It did the job but not too well.)

Details: As the README says, "The WASM target wasm32-unknown-unknown is not automatically supported". However, for things like simulation purposes, self-seeded RNGs are warranted, and as the rust-random project has a bunch of well-vetted, well-documented random algorithms plus a lot of supporting APIs, it would be great if there was a well-documented way to use them on wasm32-unknown-unknown and in other context that can't assume anything about the environment. Currently the documentation assumes that you want to get system-seeded random numbers with getrandom, which isn't necessarily true.

Note: If this is only a documentation problem, I'm happy to help fixing that. If it needs larger refactorings, let's see what we can do.

It's just a doc issue; it works fine (just disable default features). Here I used small_rng but you can use any RNG crate.

I tried to use small_rng also, but with no success. I'll try to reproduce my setup later this weekend, if not just to further my own understanding what goes wrong.

Sorry, missed about disabling the default features; I was a bit hurry yesterday, so sorry about the noise!

Thanks, closing this!
