docstring: Returns a new GraphSet with subgraphs of a graph in `obj`.
  
          The `self` is not changed.
  
          Examples:
            >>> graph1 = [(1, 2)]
            >>> graph2 = [(1, 2), (1, 4)]
            >>> graph3 = graph1 + [(2, 3)]
            >>> graph4 = [(1, 4), (2, 3)]
            >>> gs1 = GraphSet([graph1, graph2])
            >>> gs2 = GraphSet([graph3, graph4])
            >>> gs1.included(gs2)
            GraphSet([[(1, 2)]])
  
          Args:
            obj: A GraphSet or a graph (an edge list).
  
          Returns:
            A new GraphSet object.
