This PR adds methods HistoryDag.sum_rf_distances and HistoryDag.average_pairwise_rf_distance, which compute the sum of rooted RF distances over all pairs of histories in a DAG, or between two DAGs.
Also added, a method HistoryDag.history_intersect which trims the DAG to contain only the histories which are also in a passed reference DAG. This method can be run using the & operator.
