          Effectively, you give this an absolute or relative import path, it will
          import it, and then pass the resulting object to
          ``_configure_from_object``.
  
          Args:
              item (str):
                  A string pointing to a valid import path.
  
          Returns:
              fleaker.App:
                  Returns itself.
