Allow Records to reference records in the SAME table

Allow Records to reference records in the SAME table

This would make a MAJOR difference in the usefulness of ZC.  I have a hierarchy of offices, a hierarchy of positions, and a current record with a collection of prior records which must remain available.  In each of these situations a row needs to reference a row in the SAME table.  Without this feature I can't use ZC for any such apps.
