Finished ICEModelFactory basic implementation.
Made a basic implementation of ICEModelFactory, which is the new name for ModelFactory. I made the name change so that it would not collide with Apache Jena's ModelFactory. Also committed a basic test for it that checks for null values returned by the factory methods. Finally, I removed the unused AppTest class.
