to the object being descriped, not the description.
EAD: find origination when not inside did, refs #7328
Add CLI tools:promote-user-to-admin, refs #7335
Cosmetic changes
Make addSuperUser() static again

EAD export: bioghist - banish <chronlist>, refs #5094
EAD export: include place events, refs #5094
EAD export: getRole() takes no arguments

getRole() hardcodes the cultureFallback option within its body and
takes no arguments, so the array argument never did anything.
Add bulk MODS export and MODS/EAD export fixes.

Added the ability to bulk export in MODS XML format, fixed issues
with the MODS export template, made site base URL an AtoM setting,
and fixed issues with EAD export.
QubitPager method to return result rows.

Added a method to QubitPage to return result rows, rather than objects.
Useful for when paging through calculated result data.
Added per-repository description views page.

Added a repository-related page that lists the most popular descriptions
in a repository and allows page views to be filtered by date range.
