Rework Cloth Reader

[andrewkaufman]

Is there a good reason to have the AtomsCrowdClothReader as a standalone node? It seems to just add extra data onto the points coming out of the AtomsCrowdReader before piping them into the generator. Can we move this functionality to the AtomsCrowdReader instead?

After using the ClothReader in production a bit, we feel it should remain a separate node, but should not require a 3rd input on the Generator. The current graph in the example script looks like:

CrowdReader -> Generator
VariationReader -> Generator
CrowdReader -> ClothReader -> Generator

but the new proposed graph would be:

CrowdReader -> ClothReader -> Generator
VariationReader -> Generator
