Collections: Allow creating Denomination​-based collections

Paul Gibson

I'd like to be able to create Collections based on Denominations. When I look at a passage in Factbook, the Commentaries section allows me to Group by Denomination. Obviously, the data is there since it's available in Factbook. I'd like a way to be able to access this data in Collections (and the Library).

Related to this are Type and Era. I have Collections for Type based on Community Tags, but it's possible some commentaries don't have Community Tags, so if there are official tags, they should be accessible.
