Slightly more optimized simplex noise cg lib based off this one: http://forum.unity3d.com/threads/2d-3d-4d-optimised-perlin-noise-cg-hlsl-library-cginc.218372/

	#ifndef NOISE_SIMPLEX_FUNC
	#define NOISE_SIMPLEX_FUNC
	/*

	Description:
	Array- and textureless CgFx/HLSL 2D, 3D and 4D simplex noise functions.
	a.k.a. simplified and optimized Perlin noise.

	The functions have very good performance
	and no dependencies on external data.
