Non-functional translation of the 5th JMonkey Tutorial to JRuby

# This file was translated from Java to JRuby (as well as using some of
# JRuby's dynamicness to get rid of repetition) from the tutorial at
# http://jmonkeyengine.org/wiki/doku.php/jme3:beginner:hello_simpleapplication

require 'java'

# Import some JMonkey classes from a list

Thanks for sharing! It'd be interesting too see the other tutorials if you got them translated too, thank you!
