docs: Get info for lists a user is a member of.
  
          This is similar to :meth:`user_lists` but with a few differences:
  
              #. It returns list info objects instead of list names.
              #. It has an option to fully resolve a user's list hierarchy. That
                 is, if a user is a member of a nested list, this method can
                 retrieve both the nested list and the parent lists that contain
                 the nested list.
  
          Args:
              username (str): The MIT username of the user
              member_type(str): The type of user, "USER" or "STRING"
              recursive(bool): Whether to fully resolve the list hierarchy
              max_return_count(int): limit the number of items returned
  
          Returns:
              list of dicts: info dicts, one per list.
