                    stored in lists, doing away with the explicit distinction
                    between "primary" and "secondary" items.  This has 
                    involved a significant change to the API (a simplification
                    overall).

              [API] Added a new GroupedStackedBarRenderer class, which also
                    called for changes in the CategoryItemRenderer interface.
                    
27-Apr-2004 : [API] In XYPlot, datasets, renderers and axes are now stored in 
                    lists, doing away with the explicit distinction between
                    "primary" and "secondary" items.  This has involved a
                    significant change to the API (a simplification overall).
                    
              [NEW] Added relative pie chart contributed by Benoit Xhenseval
                    (see RFE 942195).

                    serialization issues for both.

21-Apr-2004 : [NEW] Barak Naveh has contributed word-wrapping of legend items. 
                    To use it, see the StandardLegend.setPreferredWidth() 
                    method. The org.jfree.chart.demo.LegendManiaDemo shows how 
                    it works.
                    
              [NEW] Added CategoryStepRenderer class (plus 
                    CategoryStepChartDemo.java) contributed by Brian Cole.

              [BUG] Changed the TextUtilities.createTextBlock() method to use

01-Mar-2004 : [API] Moved HistogramBin and HistogramDataset from org.jfree.data
                    to org.jfree.data.statistics.  Additional changes were made to
