    *  A plugin for jqPlot to render a category style axis, with equal pixel spacing between y data values of a series.
    *  
    *  To use this renderer, include the plugin in your source
    *  > <script type="text/javascript" language="javascript" src="plugins/jqplot.categoryAxisRenderer.js"></script>
    *  
    *  and supply the appropriate options to your plot

        // prop: sortMergedLabels
        // True to sort tick labels when labels are created by merging
        // x axis values from multiple series.  That is, say you have
        // two series like:
        // > line1 = [[2006, 4],            [2008, 9], [2009, 16]];
        // > line2 = [[2006, 3], [2007, 7], [2008, 6]];
        // If no label array is specified, tick labels will be collected
        // from the x values of the series.  With sortMergedLabels
        // set to true, tick labels will be:
        // > [2006, 2007, 2008, 2009]
        // With sortMergedLabels set to false, tick labels will be:
        // > [2006, 2008, 2009, 2007]
        //
        // Note, this property is specified on the renderOptions for the 
        // axes when creating a plot:
        // > axes:{xaxis:{renderer:$.jqplot.CategoryAxisRenderer, rendererOptions:{sortMergedLabels:true}}}
