That createBegin language is in the TemplateModelSwarm. 
I imagine that is where it came from.    See Here:

+createBegin: (id) aZone {
  TemplateModelSwarm * obj;
  id <ProbeMap> probeMap;

  obj = [super createBegin: aZone];
...........

I've often wondered why it is done that way.

What would you think he should do instead in the case of his "nested"
Swarm classes?  I wonder if it ought to directly call the Swarm class in
the SmlSwarm?  I mean include Swarm.h and then do [Swarm createBegin:
aZone] ?

This is interesting because, like other examples I've stumbled into
lately, one has to alter/change some of the boilerplate code from the
swarmapps to get jobs done.
