+*
+*
+* 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
+*   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.
+*   tagValuesAttribute - Name of tag attribute to check for data values - Defaults to 'values'
+*   enableTagOptions - Whether to check tags for sparkline options
+*   tagOptionPrefix - Prefix used for options supplied as tag attributes - Defaults to 'spark'
+*   disableHiddenCheck - If set to true, then the plugin will assume that charts will never be drawn into a
+*           hidden dom element, avoding a browser reflow
+*   disableInteraction - If set to true then all mouseover/click interaction behaviour will be disabled,
+*       making the plugin perform much like it did in 1.x
+*   disableTooltips - If set to true then tooltips will be disabled - Defaults to false (tooltips enabled)
+*   disableHighlight - If set to true then highlighting of selected chart elements on mouseover will be disabled
+*       defaults to false (highlights enabled)
+*   highlightLighten - Factor to lighten/darken highlighted chart values by - Defaults to 1.4 for a 40% increase
+*   tooltipContainer - Specify which DOM element the tooltip should be rendered into - defaults to document.body
+*   tooltipClassname - Optional CSS classname to apply to tooltips - If not specified then a default style will be applied
+*   tooltipOffsetX - How many pixels away from the mouse pointer to render the tooltip on the X axis
+*   tooltipOffsetY - How many pixels away from the mouse pointer to render the tooltip on the r axis
+*   tooltipFormatter  - Optional callback that allows you to override the HTML displayed in the tooltip
+*       callback is given arguments of (sparkline, options, fields)
+*   tooltipChartTitle - If specified then the tooltip uses the string specified by this setting as a title
+*   tooltipFormat - A format string or SPFormat object  (or an array thereof for multiple entries)
+*       to control the format of the tooltip
+*   tooltipPrefix - A string to prepend to each field displayed in a tooltip
+*   tooltipSuffix - A string to append to each field displayed in a tooltip
+*   tooltipSkipNull - If true then null values will not have a tooltip displayed (defaults to true)
+*   tooltipValueLookups - An object or range map to map field values to tooltip strings
+*       (eg. to map -1 to "Lost", 0 to "Draw", and 1 to "Win")
+*   numberFormatter - Optional callback for formatting numbers in tooltips
+*   numberDigitGroupSep - Character to use for group separator in numbers "1,234" - Defaults to ","
+*   numberDecimalMark - Character to use for the decimal point when formatting numbers - Defaults to "."
+*   numberDigitGroupCount - Number of digits between group separator - Defaults to 3
+*
+* 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
+*       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
+*       drawNormalOnTop - Draw the normal range above the chart fill color if true
+*       defaultPixelsPerValue - Defaults to 3 pixels of width for each value in the chart
+*       highlightSpotColor - The color to use for drawing a highlight spot on mouseover - Set to null to disable
+*       highlightLineColor - The color to use for drawing a highlight line on mouseover - Set to null to disable
+*       valueSpots - Specify which points to draw spots on, and in which color.  Accepts a range map
+*
+*   bar - Bar chart.  Options:
+*       barColor - Color of bars for postive values
+*       negBarColor - Color of bars for negative values
