Standard RCA Stitcher rules

All of the standard RCA Stitcher rules operate with reference to the in-scope trigger event, and this event is referenced using the value in its Serial field. These stitcher rules work with a copy of the trigger event and this copy of the event is not actually updated during processing. Following processing the copy of trigger event simply goes out of scope without being updated. All updates are made to the original trigger event held in the RCA plug-in mojo.events table.
