v1.12.8

-- Add printing of subject level p-values when they are made available after processing stream calculation. Next step is to display them in a GUI table.

-- Fix and simplify incorrect Save methods when calculating procStream and then saving for just one subject or one run. Delete SaveCurrElem() and Save() methods for SubjClass and RunClass. Basically it only makes sense to have a group level Save method because there can't be such a thing as saving parts of a group which just invites inconsistencies. You always save group as a whole.

-- Fix automatically updating ProcStreamOptionsGUI (if it's currently active) when processing stream is changed and saved via ProcStreamEditGUI.

-- Fix matrix inconsistency error in hmrR_OD2Conc.m. This probably needs to be fixed in homer2 as well.
