Preserve old nodes' positions on layout re run, when a new set of nodes are added to the graph? #40

I basically want to know if there is a functionality in dagre like randomize: false which is available in layouts like cose-bilkent where the old node positions are respected when the layout is re run after adding a new set of nodes(more specifically, after expanding a compound node using expand-collapse.

I've just been playing with this for a few minutes, but I found sorting the nodes to help. In my case each node has an id. The graph appears, on a small graph of about 10 nodes, stable.

This is up to how dagre itself works. If you want new dagre features, you should post issues on the dagre issue tracker.
