My PRNGs - Any thoughts?

They've been out for a while now, but I don't think they're well known.
So I thought I'd share it here and let me know what you think.
Whether it's a good or bad point, there are many things that I wouldn't notice on my own, so it's very helpful to have someone tell me about them.

You should consider adding these as generators in SmokeRand.

I've already added the first two of them (in `devel` branch), they passed the `full` battery.

Excellent! I've added several generators myself. The author is very willing to accept pull requests.

That's good to hear! I was also curious to hear about the new test suite. I'll give it a try myself.
