    The fallback controller for vigiboard.

    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)

            except mako.exceptions.TopLevelLookupException:

                abort(404)
