038: * -------
039: * 11-Jun-2003 : Version 1 (DG);
040: * 23-Jul-2003 : Renamed BooleanTable --> BooleanList and now extends
041: * ObjectList (DG);
042: * 13-Aug-2003 : Now extends new class AbstractObjectList (DG);
043: * 21-Oct-2004 : Removed duplicate implementation of Cloneable and Serializable,
044: * AbstractObjectList already implements that.
