It would be great if there were a merge patrons feature. If you accidentally
end up with one patron with two cards it would be nice to merge their records
together so that you don't lose their history or holds or anything.
This patch adds a basic patron merge feature. It attempts to relink all patron
related tables from the patron(s) to be merged. It does not attempt to relink
librarian account related tables at this time. This feature does not attempt to
automatically resolve issues such as duplicate holds. Such a feature could
build upon this one though.
1) Apply this patch
2) Find two or more patrons
3) Perform a patron search that will bring them up on the same page of results,
or add them all to a list of patrons.
4) Use the 'merge' button to begin the merging process
5) Choose a patron to keep
6) Verify the deleted patrons data ( checkouts, holds, etc )
are now linked to the kept patron
