7 * Version 1.3   -   Updated: Mar. 23, 2010
8 *
9 * This Plug-In will create a custom tooltip to replace the default
10 * browser tooltip. It is extremely lightweight and very smart in
11 * that it detects the edges of the browser window and will make sure
12 * the tooltip stays within the current window size. As a result the
13 * tooltip will adjust itself to be displayed above, below, to the left 
14 * or to the right depending on what is necessary to stay within the
15 * browser window. It is completely customizable as well via CSS.
