*
* This Plug-In will create a custom tooltip to replace the default
* browser tooltip. It is extremely lightweight and very smart in
* that it detects the edges of the browser window and will make sure
* the tooltip stays within the current window size. As a result the
* tooltip will adjust itself to be displayed above, below, to the left 
* or to the right depending on what is necessary to stay within the
* browser window. It is completely customizable as well via CSS.
