    The fallback controller for ScriptsPony.
    
    By default, the final controller tried to fulfill the request
    when no other routes match. It may be used to display a template
    when all else fails, e.g.::
    
        def view(self, url):
            return render('/%s' % url)
    
    Or if you're using Mako and want to explicitly send a 404 (Not
    Found) response code when the requested template doesn't exist::
    
        import mako.exceptions
        
        def view(self, url):
            try:
                return render('/%s' % url)
