* A Shipment represents the combined key/data pair for a shipment entity.

* <p> In this sample, Shipment is created from the stored key/data entry
* using TupleSerialEntityBinding. See {@link SampleViews.PartBinding} for
* details.
* </p>
*
* <p> The binding is "tricky" in that it uses this class for both the stored
* data entry and the combined entity object. To do this, the key field(s)
* are transient and are set by the binding after the data object has been
* deserialized. This avoids the use of a ShipmentData class completely. </p>
*
* <p> Since this class is used directly for data storage, it must be
* Serializable. </p>
