+//   This is a class for run control in Tasking for multi-threaded runs
+//   It extends RunManager re-implementing multi-threaded behavior in
+//   key methods. See documentation for RunManager
+//   Users initializes an instance of this class instead of RunManager
+//   to start a multi-threaded simulation.
