-*
-*
-* 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])
-*
-* Values can also be specified in an HTML comment, or as a values attribute:
-*    <p>Sparkline: <span class="sparkline"><!--1,4,6,6,8,5,3,5 --></span></p>
-*    <p>Sparkline: <span class="sparkline" values="1,4,6,6,8,5,3,5"></span></p>
-*    $('.sparkline').sparkline();
-*
-* 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] ])
-*
-* By default, options should be passed in as teh second argument to the sparkline function:
-*   $('.sparkline').sparkline([1,2,3,4], {type: 'bar'})
-*
-* Options can also be set by passing them on the tag itself.  This feature is disabled by default though
-* as there's a slight performance overhead:
-*   $('.sparkline').sparkline([1,2,3,4], {enableTagOptions: true})
-*   <p>Sparkline: <span class="sparkline" sparkType="bar" sparkBarColor="red">loading</span></p>
-* Prefix all options supplied as tag attribute with "spark" (configurable by setting tagOptionPrefix)
-*
-* 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

-*   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.

-*   enableTagOptions - Whether to check tags for sparkline options
