Added new primitive LinkedList class that performs better than the java.util.LinkedList class.  Added a unit test that runs on both the Crater Dog primitive list classes and the java list classes.  This validates that all classes are interoperable and also provides loose performance numbers comparing them.
Added new primitive Hashtable class that performs better than the java.util.HashMap class.  Added a unit test that runs on both the Crater Dog primitive map classes and the java map classes.  This validates that all classes are interoperable and also provides loose performance numbers comparing them.
Completed the unit tests for the new HashTable class.
