/* YOU SHOULD DELETE THIS CHANGELOG TO REDUCE FILE SIZE:
* v1.2.1 altered:  2nd July 07. added hide() before animate to make work for jQuery 1.1.3. See comment in 'over' function.
* v1.2.2 altered:  2nd August 07. changed over function .find('ul') to .find('>ul') for smoother animations
* 				    Also deleted the iframe removal lines - not necessary it turns out
* v1.2.3 altered:  jquery 1.1.3.1 broke keyboard access - had to change quite a few things and set display:none on the
*				    .superfish rule in CSS instead of top:-999em
* v1.3	: 		    Pretty much a complete overhaul to make all original features work in 1.1.3.1 and above.
*				    .superfish rule reverted back to top:-999em (which is better).
* v1.3.1 altered:  'li[ul]' to $('li:has(ul)') to work with jQuery 1.2
* v1.3.2: 			added onshow callback option as requested - 'this' keyword refers to revealed ul.
fixed bug whereby multiple menus on a page shared options. Now each menu can have separate options.
fixed IE6 and IE7 bug whereby under certain circumstances => 3rd tier menus appear instantly with text missing when revisited
* v1.3.3: 			altered event attachment selectors for performance increase on menu setup.
* v1.3.4: 			fixed pathClass bug as current path was not being restored. Still doesn't if using keyboard nav (will work on that).
