Cubic interpolation bug

[zirik]

I was getting weird results from the Curve module so I went digging through the code.
This is the return statement from the CubicInterp function in the original libnoise:
return p * a * a * a + q * a * a + r * a + s;
And this is the return statement from the Cubic method of NoiseMath in SharpNoise:
return (p * a * a * a) + (q * a * a * a) + (r * a) + s;
It seems q is being multiplied by a one too many times. Removing the extra multiplication fixed the issues I was having.

Thanks - this will be fixed in the next release. Whenever that is...
