+* 
+*
+* Usage: 
+*  $(selector).sparkline(values, options)
+*
+* If values is undefined or set to 'html' then the data values are read from the specified tag:
+*   <p>Sparkline: <span class="sparkline">1,4,6,6,8,5,3,5</span></p>
+*   $('.sparkline').sparkline();
+* There must be no spaces in the enclosed data set
+*
+* Otherwise values must be an array of numbers or null values
+*    <p>Sparkline: <span id="sparkline1">This text replaced if the browser is compatible</span></p>
+*    $('#sparkline1').sparkline([1,4,6,6,8,5,3,5])
+*    $('#sparkline2').sparkline([1,4,6,null,null,5,3,5])
+*
+* For line charts, x values can also be specified:
+*   <p>Sparkline: <span class="sparkline">1:1,2.7:4,3.4:6,5:6,6:8,8.7:5,9:3,10:5</span></p>
+*    $('#sparkline1').sparkline([ [1,1], [2.7,4], [3.4,6], [5,6], [6,8], [8.7,5], [9,3], [10,5] ])
+*
+* Supported options:
+*   lineColor - Color of the line used for the chart
+*   fillColor - Color used to fill in the chart - Set to '' or false for a transparent chart
+*   width - Width of the chart - Defaults to 3 times the number of values in pixels
+*   height - Height of the chart - Defaults to the height of the containing element
+*   chartRangeMin - Specify the minimum value to use for the Y range of the chart - Defaults to the minimum value supplied
+*   chartRangeMax - Specify the maximum value to use for the Y range of the chart - Defaults to the maximum value supplied
+*   chartRangeClip - Clip out of range values to the max/min specified by chartRangeMin and chartRangeMax
+*   chartRangeMinX - Specify the minimum value to use for the X range of the chart - Defaults to the minimum value supplied
+*   chartRangeMaxX - Specify the maximum value to use for the X range of the chart - Defaults to the maximum value supplied
+*   composite - If true then don't erase any existing chart attached to the tag, but draw
+*           another chart over the top - Note that width and height are ignored if an
+*           existing chart is detected.
+*
+* There are 7 types of sparkline, selected by supplying a "type" option of 'line' (default),
+* 'bar', 'tristate', 'bullet', 'discrete', 'pie' or 'box'
+*    line - Line chart.  Options:
+*       spotColor - Set to '' to not end each line in a circular spot

+*       spotRadius - Radius in pixels
+*       lineWidth - Width of line in pixels
+*       normalRangeMin 
+*       normalRangeMax - If set draws a filled horizontal bar between these two values marking the "normal"
+*                      or expected range of values
+*       normalRangeColor - Color to use for the above bar
+*       defaultPixelsPerValue - Defaults to 3 pixels of width for each value in the chart
+*
+*   bar - Bar chart.  Options:

+*       zeroAxis - Centers the y-axis around zero if true
+*
+*   tristate - Charts values of win (>0), lose (<0) or draw (=0)
