       * Class: $.jqplot.PointLabels
       * Plugin for putting labels at the data points.
       * 
       * To use this plugin, include the js
       * file in your source:
       * 
       * > <script type="text/javascript" src="plugins/jqplot.pointLabels.js"></script>
       * 
       * By default, the last value in the data ponit array in the data series is used
       * for the label.  For most series renderers, extra data can be added to the 
       * data point arrays and the last value will be used as the label.
       * 
       * For instance, 
       * this series:
       * 
       * > [[1,4], [3,5], [7,2]]
       * 
       * Would, by default, use the y values in the labels.
       * Extra data can be added to the series like so:
       * 
       * > [[1,4,'mid'], [3 5,'hi'], [7,2,'low']]
       * 
       * And now the point labels would be 'mid', 'low', and 'hi'.
       * 
       * Options to the point labels and a custom labels array can be passed into the
       * "pointLabels" option on the series option like so:
       * 
       * > series:[{pointLabels:{
       * >    labels:['mid', 'hi', 'low'],
       * >    location:'se',
       * >    ypadding: 12
       * >    }
       * > }]
       * 
       * A custom labels array in the options takes precendence over any labels
       * in the series data.  If you have a custom labels array in the options,
       * but still want to use values from the series array as labels, set the
       * "labelsFromSeries" option to true.
       * 
       * By default, html entities (<, >, etc.) are escaped in point labels.  
       * If you want to include actual html markup in the labels, 
       * set the "escapeHTML" option to false.
       *
