* @desc Displays a clueTip on mouseover of all elements with class="clue". The hovered element gets a class of "highlight" added to it (so that it can be styled appropriately. This is esp. useful for non-anchor elements.). The clueTip is "sticky," which means that it will not be hidden until the user either clicks on its "close" text/graphic or displays another clueTip. The "close" text/graphic is set to diplay at the bottom of the clueTip (default is top) and display an image rather than the default "Close" text. Moreover, the body of the clueTip is truncated to the first 60 characters, which are followed by an ellipsis (...). Finally, the clueTip retrieves the content using POST rather than the $.ajax method's default "GET."
