Global threshold applied in ExtractNetMet

In ExtractNetMet line 72 a global threshold of 0.0001 is applied to the adjacency matrix. Should this be removed now we are using probabilistic thresholding

Part of the reason for this is to make findNodeDegEdgeWeight work, however just putting in a very small number e.g. 0.00000001 into edge_thresh for findNodeDegEdgeWeight does the same
