          Import config values from a dictionary.
  
          When ``as_defaults`` is set to ``True``, the values
          imported will be set as defaults. This can be used to
          declare the sections and items of configuration.
          Values of sections and items in ``dictionary`` can be
          dictionaries as well as instances of :class:`.Item` and
          :class:`.Config`.
