Speed Bumps API concept

// This should be all a theme has to do to register a speed bump and get it inserted

register_speed_bump( 
    'polar', // speedbump ID, just a hook in case it needs to be disabled on case-by-case basis anywhere else
    10,      // priority. WP uses priority integers like this a lot to look
             // through arrays. The $_speed_bumps array would be sorted by
             // priority and looped through, so that the speed bumps with the
             // lowest priority get inserted first.
    array(
        // $args array. See http://codex.wordpress.org/wp_parse_args for an
        // idea how to use this pattern

        // callback, required if it returns any output
        'callback' => function() { return '<div id="polar"></div>'; }

        // optional overrides to default settings.
