minor bugfix in CheckinScheduleBuilder
fixed bug in GroupList block where the descendants of a Group wouldn't work because the operation was getting done while the qry was still in Database SQL mode.  Also rewrote the code that determines of items are a descendant of a parent (added a Trello card to discuss doing this as a general pattern in these situations)
