This class contains information on the configuration, i.e set of nodes or simply site definition.
Users are responsible for guaranteeing that information encapsulated by different Gcs_xcom_nodes is properly defined. In the sense that the member identifier, the unique identifier and the address uniquely identify a node and the same holds for any combination of those three.
Nodes inserted in this set are copied and stored in a vector object. Currently, we don't check whether the same node is inserted twice or not and as such duplicated entries are allowed. Users are responsible for guaranteeing that duplicated entries are not inserted.
