Eutester4j Template test

Created a very simple test template for using Eutster4j. Does not even
rely on TestNG is a stand alone application/test class using Eutester4J
library.

This checkin also conatins a fix to the getLastLaunchedInstance()
method.  Previously the instance ID's were compared which was fine for
AWS but euca may not always give ordered instance ID's so now instance
launch time is used as comparator.
