You can send an Activity (the object you get back from activateIn) the
the messages run, terminate, step, next, and stop.  In a simulation
set up to run in batch, you then may need to introduce some way to
restart it (e.g.  wait on standard input and then call run again).

Otherwise, if you have a non-batch simulation and want an programmed
way to stop the simulation, here's an example.  (See the
swarm.simtoolsgui.ControlPanel reference for the other messages.)

        return this;
    }

                       "setStateStopped",
                       true));
      
    } catch (Exception e) {
      e.printStackTrace (System.err);
    }
    schedule.at$createAction (0, group);
    return this;
  }
  
  public Activity activateIn (Swarm swarmContext) {
    super.activateIn (swarmContext);
    
    schedule.activateIn (this);
    stopSchedule.activateIn (this);
    return getActivity ();

  static void main (String []args) {

    GUISwarm guiSwarm = new TestControlPanel (Globals.env.globalZone);

    guiSwarm.buildObjects ();
    guiSwarm.buildActions ();
    guiSwarm.activateIn (null);
    guiSwarm.go ();
  }
}
