 /**
  * Uses a GeoIP database to get a visitor's location based on their IP address.
  *
  * This function will return different results based on the data used and based
  * on how the GeoIP module is configured.
  *
  * If a region database is used, it may return the country code, region code,
  * city name, area code, latitude, longitude and postal code of the visitor.
  *
  * Alternatively, only the country code may be returned for another database.
  *
  * If your HTTP server is not configured to include all GeoIP information, some
  * information will not be available to Piwik.
  *
  * @param array $info Must have an 'ip' field.
  * @return array
