 *
 * QualifiedAssociation is a subclass of DBAssociation which is designed to
 * replace the association created by the DBKit palette between a fetch  
 * group from a master table and the fetch group from a detail table.  Pass 
 * the detail fetch group into the init method for this object which will find  
 * the current association for that fetch group and replace that association 
 * with this new one.  After the initialization, the new association is owned
 * by the DBModule, and the old association has been freed.
 *
 * The added value of this association is to place an additional qualifier
 * on the fetch of the detail records.  This qualifier can be set and accessed
 * via the setQualifier: and qualifier methods.
