    // Insert some javascript to first retrieve the user's lat/lon coords,
    // HTML5 style (requiring the user to accept a browser prompt) and then
    // optionally (default) use Google Maps API to reverse-geocode the lat/lon
    // into a street address.
    // This is all done via client-side calls, so the Drupal server will not
    // rake up any calls against its Google-imposed quotum, i.e. the
    // OVER_QUERY_LIMIT.
    // When done, the javascript calls us back on the default menu callback,
    // '/js/ip_geoloc/current_location', which receives the geolocation data
    // from the Google Maps call via the $_POST variable and stores it on the
    // session.
    // Naturally all of this will only work if the browser is connected to
    // the internet and has javascript enabled.
