Simplexnoise

As copied from the original C implementation by Stefan Gustavson:

This package implements "Simplex Noise" as presented by Ken Perlin at a relatively obscure and not often cited course session "Real-Time Shading" at Siggraph 2001 (before real time shading actually took on), under the title "hardware noise". The 3D function is numerically equivalent to his Java reference code available in the PDF course notes, although I re-implemented it from scratch to get more readable code. The 1D, 2D and 4D cases were implemented from scratch by me from Ken Perlin's text.
