   * This class is the public entry point by which workflow communicates status changes, 
   * level changes, and other useful changes.
   * 
   * Note that this class delegates all of these activities to the PostProcessorService, 
   * which does the actual work.  This is done to ensure proper transaction scoping, and 
   * to resolve some issues present otherwise.
   * 
   * Because of this, its important to understand that a transaction will be started at 
   * the PostProcessorService method call, so any work that needs to be done within the 
   * same transaction needs to happen inside that service implementation, rather than 
   * in here.
