Simplex Noise

Now that we've worked with Value, Perlin, and Curl noise, I though it was time to cover Simplex noise. No mysteries, no unexplained hairy factors.

Having said that, the Q & A aren't done yet because I ran out of time. If you want me to elaborate on anything, mention it and I'll include it. The math is as straightforward as possible, but there's a lot and I might have moved too fast in some places.
