Title: Material exceptions

Previously, if a user changed the `material` property of a primitive to `undefined`, we silently changed it to the default material. I don't think this is the right behavior; we don't do it with other properties. I changed `update` to throw an exception instead.

I don't think this is important enough to update CHANGES.md, but I can if folks want.

Sensors still don't have tests, I know. `update` needs better doc throughout, but that is dependent on the DDR.
