"Prints a summary of vertex degrees in `graph` to standard-out. Both the average degree of all vertexes and the average degree between all pairs of vertex classes \(as determined by the vertex-classifier\) will be printed. The `edge-size` parameter is passed on to `vertex-degree` to allow for weighted edges."
