Community strength and partition density

[yy]

It will be useful if the program creates two files containing community strength and partition density for each community at the optimal threshold (or given threshold). The community strength is the similarity value when the community is created.

Maybe we should add a --stats switch to record info about each community. We could start with the same .mc_nc file that the C++ creates and add a third column containing the community strength.

I agree. For the strength,

1. We need to record when the community formed.
2. Strength does not seem to be a good measure. Imagine a very strong community + a link that is attached to the community later. In this case, the strength becomes very weak due to the attachment of the link.
