[Eeglablist] interpolating channels by scripts

[Tarik S Bel-Bahar]

Hi Jose, this might be useful to you. When you look at eegh output you
will often see a line that updates the EEG and ALLEEG structures.
Please make sure not to skip it, as it might causing your updating
problems. You can also explore more info about this command in the
tutorial.
Note that this is not equivalent to the eeg_checkset command, though
it may run it as part of the eeg_store.

[ALLEEG, EEG, CURRENTSET] = eeg_store( ALLEEG, EEG, 0 );
