/* * * * * * * * addHoverMethod functions * * * * * * * *

   Internet Explorer (through version 6, at least) recognizes the 
   CSS2 'hover' state only for anchor elements, preventing the use
   of the :hover pseudoclass for other elements.
   
   These functions add a method to one or more elements that applies
   a class of 'hover' to the element(s) on mouseover. The purpose is 
   to mirror the behavior of the 'hover' state for the specified 
   element(s). To take advantage of this, for each :hover reference
   in the CSS rules, an application should also be included for the
   .hover class. 
   
   For example, if a rule needs to be applied to list items (<li>) 
   when they are moused over, the method should be added to the 
   particular items (see instructions below) and the stylesheet 
   should include both li:hover and li.hover as shown:

     li:hover, li.hover {...}
