NF: graphpartition will raise error if passed weighted matrix, new code to find solitary (unconnected) nodes
RF: cleaning up doc strings
NF: working find correct stopping rate for Newman Spectral partition
NF: change in delta Q esitmate, provide feedback to user, this will be removed in future release
RF: fix GraphPartition to calc find_unconnected_nodes no find_solitary based on suggestion by @kbegany
BF: use better estimate of delta modularity in spectral method, remove broken test that was not testing the correct logic
