-- Add plotting of aux data to MainGUI.
-- Move plot probe control in MainGUI from checkbox to Tools menu where most of the other child GUIs are.
-- Fix issue in hmrG_SubjAvg where if subjects' standard deviation is empty we get matlab error when calculating dc avg. That's because now that standard deviation is a separate function, it's not guaranteed to be there if there's no standard dev function in subject-level proc stream. Added check in group-level calculation of subject standard deviation. If it's missing then all channels pass (subject standard deviation is used to calculate which channels are to far from the mean to include in group dc avg)
