The files stored in this directory are generated from the test driver gov.va.med.esr.common.util.ObjectVersioningTest.  It contains methods that generates fully populated  instances of these objects that represent the universe of serialized objects present in ESR implementation.  These .ser files are also read from the same ObjectVersioningTest to verify they can be deserialized with evolving builds.

Examples where serialization may used is:  JMS Messages (persisted to disk), Database tables (in BLOB columns), file stores, etc.
