*
* 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
*   tagOptionPrefix - Prefix used for options supplied as tag attributes - Defaults to 'spark'

*           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

*   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

*       normalRangeColor - Color to use for the above bar
*       drawNormalOnTop - Draw the normal range above the chart fill color if true
