So here are the changes I'd suggest.  The problem was that you had
ModelSwarm.h included in the files below, which made the includes happen
in a different order than you probably anticipated.  The only time you
really ought to include a ModelSwarm in an agent type file is when
you need the agent to seem some global state or do behind-the-scenes
global bookkeeping, etc.

Note the last chunk was a workaround fix to get the thing to run.
It can happen modelSwarm isn't initialized at that point in Post.m.
The other printf thing is just a picky typing thing you'll see on some
systems.

Also I changed "food" to not conform to the Discrete2d protocol because
you use it with some additional methods from FoodSpace.  So I statically
typed it.

To apply the patches run:

$ cd bandarch
$ patch -p1 < the-file-below
