I unpacked the Swarm file and put the NodeItem.m file into the directory
with the code for my model. It allowed me to see what was going on.

agentID wasn't NULL, but it was a number. I thought I could just recast it
as a string using (const char *) but that apparently didn't work.
I am solving the problem by just using sprintf as was done in the Bank model.
Thanks for helping me solve this and learn a little more about Swarm on the
way.
New questions:
1. I want to make the nodes very small. What is the best way to do this?
2. My idea is to use setFont to set a very small font. Where can I find a
list of the fonts, their names, and characteristics? How do I set the
fontsize?
3. Also where do I find the list of colors that I can set? I found a file
labeled rgb.txt in c:\emacs\etc\. Are these the names and colors that
Swarm uses?
