** 001 GES 20080522   @38524 Created initial version which represents the condition/action pair
**                           that defines how blocks react to conditions.
** 002 GES 20080702   @39063 Support cases where 2 different labels are targets (for UNDO and
**                           the action).
** 003 GES 20160518          Code formatting cleanup.
