NurbsCurves not obeying schema

[bfloch]

Hi,
As opposed to pxr's plugin the round trip of curves works with AL_USDMaya within Maya. Thanks.
However I noticed that the import/export does not seem to obey the schema/spec for NurbsCurves but instead just moves Maya's data back and forth:

Any plans to adapt? The problem would become obvious once we have the curves represented in hydra.
