This is exactly what happens if you use contract.vertices() with the membership
vector. contract.vertices() expects a vector that tells the "new" ID of each
vertex after the contraction. So, if the value belonging to a certain vertex in
the membership vector is X, then the vertex will be merged into the "new" node
with ID=X in the contracted graph.

Best,
