 * Changes (from 24-Aug-2001)
 * --------------------------
 * 24-Aug-2001 : Added standard source header. Fixed DOS encoding problem (DG);
 * 07-Nov-2001 : Separated the JCommon Class Library classes, JFreeChart now 
 *               requires jcommon.jar (DG);
 * 21-Nov-2001 : Allowed for null axes (DG);
 * 27-Aug-2002 : Small update to get existing axis properties working 
 *               again (DG);
 * 26-Nov-2002 : Changes by David M. O'Donnell for ContourPlot (DG);
 * 17-Jan-2003 : Plot classes have been moved into a separate package (DG);
 * 08-Sep-2003 : Added internationalization via use of properties 
 *               resourceBundle (RFE 690236) (AL); 
 * 24-Aug-2004 : Applied patch 1014378 (DG);
 * 17-Apr-2005 : Replaced 'new Boolean' with 'BooleanUtilities.valueOf' (DG);
