the class DeepMergeCloneSerializedTest method test.

     * This test creates an object and registers it with a unit of work.  It then serializes that
     * object and deserializes it.  Adds an object onto the origional then performs serialization
     * sequence again.  Then deepMergeClone is attempted and the results are compared to verify that
     * the merge worked.
