+  * This class allows an object to validate that it is valid after
+  * deserialization has run completely for it and all dependent objects.
+  * This allows an object to determine if it is invalid even if all
+  * state data was correctly deserialized from the stream.  It can also
+  * be used to perform re-initialization type activities on an object
+  * after it has been completely deserialized.
+  *
+  * Since this method functions as a type of callback, it must be 
+  * registered through <code>ObjectInputStream.registerValidation</code>
+  * in order to be invoked.  This is typically done in the
+  * <code>readObject</code> method.
