Utility class to handle cookies.

This class contains only two instance methods. Usage example:

$storage
  ->flag(145);

  static function factory($flag) {
    if ($flag->global) {
      return new FlagGlobalCookieStorage($flag);
    }
    else {
      return new FlagNonGlobalCookieStorage($flag);
    }
  }
