Actually, you know what?  Brain fart.  When I submitted the code review, I was attempting to pull out stuff that needed to be used by the dashboard and the front end and meld it into a single generic plugin class.  Now that I _actually_ look at the code...the "generic stuff" I yanked out (plus the stuff I added) are _all_ related to suggesting terms.  `Scriblio_Authority_Suggest` is the right plan.  I'll make that change soon.
