Update to v1.2.0

[Chris Watson]

Dear all,

I have updated the package to v1.2.0. You may find the changes in the NEWS.md file.

A particularly major change to "create_mats" is the addition of a value given to "sub.thresh". You may now specify "mean" as the value, and it will keep connections that satisfy

mean(A_ij) + 2*SD(A_ij) > threshold

See the references in the User Guide (Chapter 6) for some examples in the literature.

I have also added a function to calculate the "s-core" membership, and have made available the "make_empty_brainGraph" function, which creates an empty graph for a specific atlas, with the correct name and lobe attributes.

Please let me know if you have questions, errors, etc.

Chris
