[Eeglablist] CleanLine & clean_rawdata plugins

[Tarik S Bel-Bahar]

Hello Rafal, notes below....

1. That does not sound unusual, I remember a pause when running cleanline
in the past. I doubt that it is freezing, it's probably just computing. You
may also want to grab newer versions of the function from the PREP toolbox
from mullen/kothe et al.

2. You don't need EOG for ICA, as frontal channels will pick up stereotyped
eye-artifacts anyway. So I would say if you want to use clean_rawdata, drop
EOG channels before running it. Also, just look at your ICA solutions doing
it different ways, you should not see much difference in eye-related
artifact ICs.
