Test robot export to generate UO templates

Working toward a fully templated solution for UO, I'll follow @jamesaoverton's suggestion:

> [Try using] `robot export` to generate one or more templates. I think the immediate goal should be a full conversion, so that `robot diff` shows that the current OWL and the new version from templates are exactly the same. That should reassure people. Then we can start cleaning and reorganizing.
