/* BEGIN: SUCKERFISH :hover for IE6 (used on drop-downs)
 * 
 * The suckerfish hover method mimics the :hover pseudo-class
 * for IE6 on any element by dynamically adding the sfHover class.
 * More info: http://www.htmldog.com/articles/suckerfish/hover/
 * 
 * This is globally applied for navigation, footer, and rss hovers.
 * Application is per element.  Add more here as necessary.
 * And don't forget, this is for IE6 only.
