I finally figured it out.
This script link:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" type="text/javascript"></script>
Muse appear BEFORE the Zurb Foundation 4 script link:
<script src="js/foundation.min.js"></script
So, the correct implementation would look like this:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" type="text/javascript"></script>
<script src="js/foundation.min.js"></script>
Such a crazy small, stupid detail cause such a huge waste of time!
If you add the link AFTER, then Zurb Foundation 4 WILL NOT WORK.
