*	This plugin is designed to make the Suckerfish method for CSS
*	cross browser compatible (ahem... IE6). As long as your CSS
*	code is cross-browser compliant and you have set the appropriate
*	'hover' class (i.e. .sfHover) for Fish to use, all you will need is:
*	@example
*		jQuery(document).ready(function() {
*			$([selector for parent menu]).fish();
*		});
*	and thats it!
