* Strategy interface used by {@link PojoCodec} to configure registrations

* By default, user defined types are not registered to Kryo.
* Registration allows a unique ID (small positive integer is ideal) to represent the type
* in the byte stream. In a distributed environment, all Kryo instances must maintain a
* consistent registration configuration in order for serialization to function properly.
* Registrations can result in better performance in demanding situations,
* but requires some care to maintain. Use this feature only if you really need it.
