Added support for gathering face-varying patch points to the Far::EndCap*PatchFactory classes. Also, changed these classes to compute varying stencils optionally, since separate varying stencils are not needed for face-varying patches. Also, removed a no longer used stateless factory method from the EndCapGregoryBasisPatchFactory.
