    A NodeManager is responsible for managing a set of Nodes.
    There can be several NodeManagers (the NM is not a singleton).
    NodeManagers are always responsible for a certain node type,  e.g.
    Node::nodeTypeDBService() (default) or NodeType::nodeTypeOriginal().

    By default the NodeManager is initialized for the NodeType ~DBService~.
