merge 2 versions: EDF and SET

[christinerogers]

need to decide:

• merging divergent UIs from set2bids and eeg2bids

• maybe 1 week for an expert

• design discussion : June 14

[christinerogers]

what needs to be done, june 14:

• add Detection of format (just check the extension of the file, and/or Ask format)
• add Back-end support for both edf/set

There seem to be no additions to the GUI from EEG2BIDS to set2bids, from discussion June 14
