/**
 * A MultiDBObjectTransaction is a group of dbobjects that are "related" - e.g. defined
 * as being part of a foreign-key/primary-key relationship. This may be
 * master/detail or a more complex relationship, but it can be expressed as a
 * "join" operation between the tables.
 *
 * After establishing the relationships between the objects the MultiDBObject
 * can have search criteria set for it & searchAndRetrieve operations done just
 * like a 'regular' DBObject, but these operations affect the entire related
 * group of objects. At the moment, MultiDBObjects are read-only, though that
 * may change in the future.
