// Navigation - Top Nav Rollover

// This rollover code is used to activate the rollover effect over the three active top navigation buttons.  The forth button will highlight the current location of the user within the site and will have no rollover effect.  So in the HTML code around the current location button (eg. home on the home page), the onmouseover and onmouseout code will need to be removed just leaving the HREF location.
