DuplicateRecordSetTriggerHandler Methods

deleteSingleRecordSetsFuture (candidatesToDelete)
Future delete DuplicateRecordSet records with only 1 DuplicateRecordItem
deleteUnnecessaryRecordSets (candidatesToDelete)
Declare deletion in a synchronous method so it can be called from either the main handler class or an asychronous method. (DRY)
findSingleRecordSets (newRecords, oldRecordsMap)
Query for all single-item DuplicateRecordSet records
First we exclude DRS records where the DRI count was and is zero. This allows us to instantiate the record. We don't know why DRS records are also updated when they are created, but that's the situation.
Then we delete DRS records where RecordCount < 2 (0 or 1) and can do so because we allowed the creation of the DRS.
handleTrigger (newRecords, oldRecords, newRecordsMap, oldRecordsMap, triggerEvent)
Handle all trigger records
