/*****************************************************

* 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.

*

* --youngpup--
