Hmmm...  ... Hmmmmmmm...

It looks to me that the preprocessor is able to find the
SwarmObject.h and therefore resolve the inheritance relation
because 
      Heatbug.h imports space.h 
  and 
      space.h imports Discrete2d.h
  and
      Discrete2d imports swarmobject.h
  and
      swarmobject.h imports SwarmObject.h

I've tried to confirm this but there are also about a
thousand other ways for the preprocessor to find a way to
import SwarmObject.h.  I just listed the shortest path I
found. (What a tangled web we weave...)

No, Heatbug.h doesn't get anything from HeatbugObserverSwarm.h,
AFAIK.  Also, if you did decided to put everything in the
Observer then that would help you if you ran in batch mode.
The HeatbugModelSwarm is the only swarm that is in all
simulations. (see main.m)
