Curve Gradient SOP [Update] (Patreon)

Brand new implementation that uses Edge Transport SOP internally.

Edge Transport SOP is faster than Find Shortest Path SOP in this case, and makes the HDA internals a lot simpler.

There are many ways to do this in Houdini but each of these methods still miss some features to have a smooth workflow, and as such they are not enough by themselves. 

That's why Curve Gradient SOP still proves to be useful in the latest production workflows.
