* 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
* 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)
* 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)
* zeroColor - Color of bars with zero values
* nullColor - Color of bars with null values - Defaults to omitting the bar entirely
* barWidth - Width of bars in pixels
-* colorMap - Optional mappnig of values to colors to override the *BarColor values above
-* can be an Array of values to control the color of individual bars or a range map
-* to specify colors for individual ranges of values
* barSpacing - Gap between bars in pixels
* zeroAxis - Centers the y-axis around zero if true
*
