This gets the modelSwarm's bugList and tells that buglist to
"getFoodNumber". If this is the end of a createSequence method, That is
about certain to cause a crash because the bugList does not have a
method getFoodNumber.  On the other hand, if it is a
createAverageSequence method, then it does expect a list/collection in
the first argument, and it may work as long as each item in the list has
the method "getFoodNumber"

This says to the observer swarm itself, "run your getFoodNumber" and it
uses that single value.

Here is what I suggest to you.  Compare these two code examples. 1)
Heatbugs, which has createAverageSequence, to graph a summary of a group
of things, and 2) Arborgames, which uses createSequence to graph
individual things, not groups of things.
