This is a very small example NetLogo extension, written in Scala.
Make sure you have sbt installed on your system, then run sbt package to package the sample extension jar file. If the build succeeds, samplescala.jar is created.
Run sbt test to run the NetLogo language tests from the tests.txt file.
Run sbt packageZip to create a zip file with all necessary files for publishing the extension.
