Introduce a way to investigate the difference in brain networks between two groups

[Islast]

Let's say we have two cohorts of subjects, for example people with a diagnosis of depression and healthy controls. Our networks are aligned, so it is straightforward to compare the cohort A network to the cohort B network. It's less straightforward to interpret this comparison.
We plan to add a module that permutes the original data and builds up a null distribution so that differences between the two real groups can be statistically tested
