THE BOX'S MAIN HELP:
This function generates 2 dimensional noise. The return value will be float, point, vector, normal or color depending on the cast, whose component(s) lie in the range [0,1].

This must be a varying float. The default is the surface parameter, u. These are the seeds for the noise function.
B (input):
This must be a varying float. The default is the surface parameter, v. These are the seeds for the noise function.
OUT (output):
This function generates 2 dimensional noise. The return value will be float, point, vector, normal or color depending on the cast, whose component(s) lie in the range [0,1].
