  /// \brief Nauty file reader

  ///

  /// The \e geng program is in the \e gtools suite of the nauty

  /// package. This tool can generate all non-isomorphic undirected

  /// graphs of several classes with given node number (e.g.

  /// general, connected, biconnected, triangle-free, 4-cycle-free,

  /// bipartite and graphs with given edge number and degree

  /// line from the given stream and builds it in the given graph.

  ///

  /// The site of nauty package: http://cs.anu.edu.au/~bdm/nauty/

  ///

  /// For example, the number of all non-isomorphic planar graphs

  /// can be computed with the following code.

  ///\code

  /// int num = 0;

  /// SmartGraph graph;

  ///   PlanarityChecking<SmartGraph> pc(graph);

  ///   if (pc.run()) ++num;

  /// }

  /// std::cout << "Number of planar graphs: " << num << std::endl;

  ///\endcode

  ///

  /// The nauty files are quite huge, therefore instead of the direct

  /// file generation pipelining is recommended. For example,

  ///\code

  /// ./geng -c 10 | ./num_of_planar_graphs

  ///\endcode
