   4         jQuery ToolTip Demo. Demo of how to add elements and get mouse coordinates
   5         There is also a ToolTip plugin found at http://www.eyecon.ro/interface/,
   6           which uses a CSS class to style the tooltip, but shows it below the input/anchor, rather than where the mouse is
