fbm_Noise_blink_kernel

fBm noise in blink for fast computation.

This is a GPU implementation of the standard 'Noise' node in nuke. Its similar in parameters as the same basic math is used.

Its a fBm on a simplex noise. This results in comaprable but not the SAME results. 

Please feel free to edit and contact me as this is for sure not the most optimized Blink code.

Let me know how you go with it and have fun!
