class_docstr: Common behavior shared between :class:`~flask.Flask` and
  :class:`~flask.blueprints.Blueprint`.
  
  :param import_name: The import name of the module where this object
      is defined. Usually :attr:`__name__` should be used.
  :param static_folder: Path to a folder of static files to serve.
      If this is set, a static route will be added.
  :param static_url_path: URL prefix for the static route.
  :param template_folder: Path to a folder containing template files.
      for rendering. If this is set, a Jinja loader will be added.
  :param root_path: The path that static, template, and resource files
      are relative to. Typically not set, it is discovered based on
      the ``import_name``.
