/*   SimpleExample/HelloWorldMain.java

HelloWorldMain -- Simple class to get program going.

In this case, it creates a few Bug instances, and then
sends them messages to ask them to emit the traditional "hello".
 
Compile:  javac HelloWorldMain.java Bug.java
Run:      java  HelloWorldMain
Copy:     cp /users/rlr/Courses/530/Src/SimpleExample/*.java  yourDir
          (This will copy some other java files, too.)

Note: the default classpath includes "." (the current working directory)
      so the above commands are able to find the Bug class
