My intentions is to take a panelized page and use fields provided in that page to create class names on the body element.
When I preprocess the page, I don't get the original node information and can't pull the information I need.
My panelized page has 1 pane that has the node-> content pane in there.
If I could just get the NID of the current page, then it would be okay. But that doesn't even show up in the variables in the theme_preprocess_html() when a page has been panelized.
$node = menu_get_object('node');
to retrieve the loaded node from the menu router cache.
