* ypSlideOutMenu
* 3/04/2001
*
* a nice little script to create exclusive, slide-out
* menus for ns4, ns6, mozilla, opera, ie4, ie5 on 
* mac and win32. I've got no linux or unix to test on but 
* it should(?) work... 
*
* Revised:
* - 08/29/2002 : added .hideAll()
* - 04/15/2004 : added .writeCSS() to support more 
*                than 30 menus.
