  38:  * -------
  39:  * 17-Nov-2001 : Version 1 (DG);
  40:  * 22-Jan-2002 : Removed the getCategoryCount() method, updated Javadoc 
  41:  *               comments (DG);
  42:  * 18-Apr-2002 : getCategories() now returns List instead of Set (oldman);
  43:  * 23-Oct-2002 : Reorganised the code: PieDataset now extends KeyedValues 
  44:  *               interface (DG);
  45:  * 04-Mar-2003 : Now just replicates the KeyedValuesDataset interface (DG);
