+*
+* 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
+*    <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])
+*
+* 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 range of the chart - Defaults to the minimum value supplied
+*   chartRangeMax - Specify the maximum value to use for the 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
+*       minSpotColor - If set, color of spot at minimum value
+*       maxSpotColor - If set, color of spot at maximum value
+*       spotRadius - Radius 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:
+*       barColor - Color of bars for postive values
+*       negBarColor - Color of bars for negative values
+*       barWidth - Width of bars in pixels
+*       barSpacing - Gap between bars in pixels
+*       zeroAxis - Centers the y-axis around zero if true
+*
+*   tristate - Charts values of win (>0), lose (<0) or draw (=0)
+*       posBarColor - Color of win values
+*       negBarColor - Color of lose values
+*       zeroBarColor - Color of draw values
+*       barWidth - Width of bars in pixels
+*       barSpacing - Gap between bars in pixels
+*       colorMap - Optional mappnig of values to colors to override the *BarColor values above
+*
+*   discrete - Options:
+*       lineHeight - Height of each line in pixels - Defaults to 30% of the graph height
+*       thesholdValue - Values less than this value will be drawn using thresholdColor instead of lineColor
+*       thresholdColor
+*
+*   bullet - Values for bullet graphs msut be in the order: target, performance, range1, range2, range3, ...
+*       options:

+*       rangeColors - Colors to use for each qualitative range background color
+*
+*   pie - Pie chart. Options:
+*       sliceColors - An array of colors to use for pie slices
+*       offset - Angle in degrees to offset the first slice - Try -90 or +90
+*
+*   box - Box plot. Options:
+*       raw - Set to true to supply pre-computed plot points as values
+*             values should be: low_outlier, low_whisker, q1, median, q3, high_whisker, high_outlier
+*             When set to false you can supply any number of values and the box plot will
+*             be computed for you.  Default is false.
+*       showOutliers - Set to true (default) to display outliers as circles
+*       outlierIRQ - Interquartile range used to determine outliers.  Default 1.5
+*       boxLineColor - Outline color of the box
+*       boxFillColor - Fill color for the box
+*       whiskerColor - Line color used for whiskers
+*       outlierLineColor - Outline color of outlier circles
+*       outlierFillColor - Fill color of the outlier circles
+*       spotRadius - Radius of outlier circles
+*       medianColor - Line color of the median line
+*       target - Draw a target cross hair at the supplied value (default undefined)
+*      
+*   
+*       
+*   Examples:
+*   $('#sparkline1').sparkline(myvalues, { lineColor: '#f00', fillColor: false });
+*   $('.barsparks').sparkline('html', { type:'bar', height:'40px', barWidth:5 });
+*   $('#tristate').sparkline([1,1,-1,1,0,0,-1], { type:'tristate' }):
+*   $('#discrete').sparkline([1,3,4,5,5,3,4,5], { type:'discrete' });
+*   $('#bullet').sparkline([10,12,12,9,7], { type:'bullet' });
+*   $('#pie').sparkline([1,1,2], { type:'pie' });
