MGD swarm-support Dec. 10, 1999

Below is how to do an EZBin in Java.  Note this is for the current
ftp://ftp.santafe.edu/pub/swarm/2.0.1-fixes javaswarm.dll and
swarm.jar,or the latest RPM from Paul, or a build from the latest in
ftp://ftp.santafe.edu/pub/swarm/testing.  I avoid using the Swarm
collections library in Java models because straight Java libraries
will be faster and easier for Java programmers to read.

I'd also like to mention that use of GUISwarm (ObserverSwarm) only has
one purpose here: to create the GUI update mechanism that the Swarm
graphics library requires.  If you use AWT/Swing for the GUI, you
don't need to use GUISwarm or any of those conventions (buildObjects,
buildActions, go).
