Class SQLRelationLoader

public class SQLRelationLoader
extends java.lang.Object
SQLRelationLoader is a quick hack for creating and removing relation from a many-to-many relation database from ClassMolder. Eventually, it will be merged into SQLEngine. But, it requires chaning of the Persistence interface.
