This is a wrapper file which simply includes BaseHeader.tmpl so that new skins can make a Header.tmpl similar to... ...this way a skin can base itself off of the same html as the default skin but still add custom css/js @todo In the future I'd like to support something like or even just do a current file vs inc'd file comparison to make sure they aren't the same. This way we can from the "derived" Header.tmpl and not cause an recursive loop.
