Changes:
New feature:
1) Ledoit-Wolf regularized partial correlation for computing
connectivity
Bugfix:
1) Changed implementation of mutual information for computing
connectivity. Previous version (from Matlab Toolbox for Functional
Connectivity) did not scale mean data appropriately, making
connectivity estimates dependent on the means of the input data
(which it should not be). New implementation applies traditional
mean scaling before estimating connectivity. Users may want to
recompute mutual information connectivity estimates.
2) Minor bug in connectivity calculation
