[Mne_analysis] single trial artifact rejection

[Alexandre Gramfort]

Hello Jonathan,

the problem with what you described it that you're going to create
edge artifacts around the time segments you remove. You mention
single trial analysis but do you mean more "on going" data? Do you
have the notion of trial with triggers? Can you be more specific about
what you want to do?
