Very cool, but then how do I get the time of the swarm.activity.ActionToImpl
and ActionConcurrent_c instances?  I can do a getClass on the object
returned by index.next, but then since it's not really a java class, I can't
cast it and then do a getKey() on it. 

eg:
        Object thing = index.next();
      System.out.println ("event: " + thing);
      Class classOfThing = thing.getClass();
      System.out.println ("classOfThing="+classOfThing.toString());
      if  (classOfThing.toString().equals("class
swarm.activity.ActionToImpl"))
        {
        swarm.activity.ActionToImpl oneAction =
(swarm.activity.ActionToImpl) thing;
        System.out.println ("One action per time unit: "+oneAction.getKey+"
"+oneAction.toString());
        }
      else if (classOfThing.toString().equals("class ActionConcurrent_c"))
        {
        ActionConcurrent_c manyActions = (ActionConcurrent_c) thing;
        System.out.println ("Many actions in this time unit:
"+manyActions.getKey+" "+manyActions.toString());
        }
      else
        {
        System.out.println ("Thing's class "+classOfThing.toString()+" not
identified");
        }

How else do I get the key for each of the actions or concurrent actions?

What I need to do is, given a time, find the first action in the schedule
*after* that time.  Also, I need to be able to determine the last action in
a concurrent group, and if it is not a "pause", add another "pause" to the
end of group at a particular time unit.

Thanks!
