/**
 * Handles additional data and activity for shipments.
 *
 * Adds additional activity after shipment objects are loaded from,
 * saved to, or deleted from the database.  This is useful for shipment
 * modules that store method-specific shipment data in separate tables that
 * need to be kept in sync with the uc_shipments table.
 *
 * The members of the shipment object are the fields in the corresponding
 * record of the uc_shipments table, plus $shipment->packages, an array
 * of package objects as returned by uc_shipping_package_load().
 *
 * @param $op
 *   The action being taken on the shipment. One of the following values:
 *   - load: The shipment and its packages are loaded from the database.
 *   - save: Changes to the shipment have been written.
 *   - delete: The shipment has been deleted and the packages are available
 *     for reshipment.
 * @param $shipment
 *   The shipment object.
 *
 * @return
 *   Only given when $op is "load". An associative array of extra data to
 *   be added to the shipment object. Each key/value element of the array
 *   becomes a separate member of the shipment object. Elements of the array
 *   with the same key as members of the shipment object replace those members
 *   of the shipment object.
