[graph-tool] kcore decomposition for the weighted network

Is there anyway to compute the kcore decomposition for the weighted networks using graph-tool? or any similar measures like k-shell. In his work [1], Vladimir Batagelj introduces "ps-core" that accounts for the edge weights. this is the paper that is cited for the kcore_decomposition <https://graph-tool.skewed.de/static/doc/topology.html#graph_tool.topology.kcore_decomposition> method. cheers, [1] https://link.springer.com/article/10.1007/s11634-010-0079-y -- Mohsen
