[graph-tool] Dice or Jaccard similarity of vertices

Hi, Is there a method to calculate the Dice or the Jaccard similarity between *all pairs of vertices* in the graph? Similar to the similarity_dice <http://igraph.org/python/doc/igraph.GraphBase-class.html#similarity_dice> and similarity_jaccard <http://igraph.org/python/doc/igraph.GraphBase-class.html#similarity_jaccard> methods in igraph? I searched through graph_tool documentation, and google, but did not find anything. Thanks, Alexey ​
