But all Ops are Commands...?

Possible solutions:
* Expose all Commands (including Ops) that declare a menu path.
* Expose Commands which have (or do not have) a particular attribute key.
We use this for ImageJ1, adding a "no-legacy" attribute for commands which
should not be exposed from the legacy ImageJ1 user interface.

Curtis
