                               throws NetworkException
        Calculate the shortest route between two nodes in the network. If no path exists from the start node to the end node in the network, null is returned. This method returns a CompleteRoute, which includes all nodes to get from start to end. This method recalculates the graph.
        Parameters:
        gtuType - GTUType; the GTUType for which to calculate the shortest route
        nodeFrom - Node; the start node.
        nodeTo - Node; the end node.
        linkWeight - LinkWeight; link weight.
        Returns:
        the shortest route from the start Node to the end Node in the network. If no path exists from the start node to the end node in the network, null is returned.
        Throws:
        NetworkException - in case nodes cannot be added to the route, e.g. because they are not directly connected. This can be the case when the links in the network have changed, but the graph has not been rebuilt.

                                       throws NetworkException
        Calculate the shortest route between two nodes in the network, via a list of intermediate nodes. If no path exists from the start node to the end node via the intermediate nodes in the network, null is returned. This method returns a CompleteRoute, which includes all nodes to get from start to end. In case the graph for the GTUType has not yet been built, this method will call the buildGraph method.
        Parameters:
        gtuType - GTUType; the GTUType for which to calculate the shortest route
        nodeFrom - Node; the start node.
        nodeTo - Node; the end node.
        nodesVia - List<Node>; a number of nodes that the GTU has to pass between nodeFrom and nodeTo in the given order.
        Returns:
        the shortest route between two nodes in the network, via the intermediate nodes. If no path exists from the start node to the end node via the intermediate nodes in the network, null is returned.
        Throws:
        NetworkException - in case nodes cannot be added to the route, e.g. because they are not directly connected. This can be the case when the links in the network have changed, but the graph has not been rebuilt.
