The function allows you to specify an initial configuration of labels and it
also allows you to mark nodes as unlabeled in the initial configuration (by
using a negative number as its "label" instead of a positive one). Therefore,
you can cater for node additions by taking the result from the clustering
before the addition, then inserting a single -1 entry for every node that you
added to the graph, and feeding this as the initial vector for the next
iteration.
Best,
