[Mne_analysis] importing EGI Net Station EEG data into MNE

[Alexandre Gramfort]

Dear Jeff,

I am really sorry but I've never worked with EGI data so I cannot really
help more on this.

I know that Matti has recently worked to improve the mne_edf2fif command.

Hari in CC might also have some experience with this.

Cheers,
Alex
