Expose d3's stack offset to allow for percent-based stack using 'expand' - fix #225
Keep same reference on data and values for scatter
Adding interactive Guideline layer double click dispatch event.
Updating tooltip.js to accept a "footer" element.
Added feature where tooltips will highlight the row corresponding to the point your mouse is closest to.
Bumping to v 1.1.11, due to changes in the tooltip.
Remove setup of `singlePoint` variable that is not used in some of the bar models.

Additionally, this variable was being assigned as a property on the global object (`window` in browsers) instead of being declared locally with a `var` statement.
Updating tooltip content generator to use d3 select instead of manually concating strings.
Updating tooltip highlight so that the item will only highlight if the
mouse is really close to the chart point. Created a "nearestValueIndex"
function.
