// PURPOSE -----
// Looks through the page's markup to identify footnote links/ content.
// It then creates footnote buttons in place of the footnote links and hides the content.
// Finally, creates and positions footnotes when the generated buttons are pressed.
// IN ----------
// An optional object literal specifying script settings.
// OUT ---------
// Returns an object with the following methods:
// close: closes footnotes matching the jQuery selector passed to the function.
// activate: activates the footnote button matching the jQuery selector passed to the function.
// INFO --------
// Developed and maintained by Chris Sauve (http://pxldot.com)
// Documentation, license, and other information can be found at http://cmsauve.com/projects/bigfoot.
// TODO --------
// - Better handling of hover
// - Ability to position/ size popover relative to a containing element (rather than the window)
// - Compensate for zoom position on mobile
// KNOWN ISSUES -
// - Safari 7 doesn't properly calculate the scrollheight of the content wrapper and, as a result, will not
// properly indicate a scrollable footnote
// - Popovers that are instantiated at a smaller font size which is then resized to a larger one won't adhere
// to your chosen max-height (in CSS) since JS tries to keep it from running off the top/ bottom of the page
// but does so using pixel values tied to the sizes of the footnote content when it was originally activated.
// If anyone has any ideas on this, please let me know!
