< Very nice and simple skew factor for 3D

< Very nice and simple unskew factor, too

< Unskew the cell origin back to (x,y,z) space

< The x,y,z distances from the cell origin

< For the 3D case, the simplex shape is a slightly irregular tetrahedron.

< Offsets for second corner in (x,y,z) coords

< Offsets for third corner in (x,y,z) coords

< Offsets for last corner in (x,y,z) coords

< Work out the hashed gradient indices of the four simplex corners

< Calculate the contribution from the four corners
