ENH: always use eeg_loc instead of dig
FIX: loop over trials
fieldtrip2fiff should convert raw, epoched, and timelocked data + test for CTF, neuromag, EEG
enhancement: also pass elec if it's in the hdr
REVERT: use original fieldtrip magic number
works with CTF and almost with neuromag
enhancement: convert from fieldtrip to fiff, with test function
doc: clarify if it crashes when more than 60 electrodes
fix: use electrode locations for eeg
