getPredecessor function and documentation dont go along

https://gitlab.com/grogra/groimp/-/blob/master/Graph/src/main/java/de/grogra/graph/impl/Node.java?ref_type=heads#L3205

I think this should be:

public Node getPredecessor ()
{
	return findAdjacent (true, false, Graph.SUCCESSOR_EDGE| Graph.BRANCH_EDGE);
}
