An S4 class which holds information on origin-destination (OD) pairs.
Each OD pair is composed of two nodes, each belonging to one network.
All origin nodes must belong to the same origin network should be contained
in one spflow_network-class() - and likewise for the destinations.

update_dat(object, new_dat)A spflow_network_pair-class
An object to replace the existing id/data
A character indicating which of the ids to change, should be one of
c("origin", "destination", "pair").
The first characters may be used as shortcuts.
A data.frame
id_net_pairA character identifying the set of origin-destination pairs
id_orig_netA character that serves as identifier for the origin nodes
id_dest_netA character that serves as identifier for the destination network
pair_dataA data.frame containing information on origin-destination pairs
## access the data describing the node pairs
