question about activateIn:

[Paul Johnson]

I'm trying to work on more swarm guide material and find myself stumped
on a couple of things.  The help I got on ProbeMap was so great
yesterday I'm hitting you with this today.

>From HeatbugObserverSwarm, here is the method I'm curious about.


- activateIn:  swarmContext
{
  // First, activate ourselves (just pass along the context).
  [super activateIn: swarmContext];
  [heatbugModelSwarm activateIn: self];
  [displaySchedule activateIn: self];
    return [self getActivity];
}

1.  I don't know what to say about the [super activateIn: swarmContext]
command.   I've seen the tutorial material on it, of course, but it
still is difficult to explain why the super is called to do anything
here.  What would you say about it.  

2.  I am at a loss to understand why all these swarm models have return
[self getActivity].  There's no receiver doing anything with the
activity it gets. The model compiles and runs fine with return self.
What's up with that?

3.  Also, would anybody care to put some words down on what comes back
when you tell something to getActivity?
