[WIP] fix channel units for EEG and iEEG

[sappelhoff]

closes #81

Using MNE-Python Master (or soon 0.17), I will be able to fix this for BrainVision and EDF (the primary formats both for EEG and iEEG) ... and probably also for BDF and EEGLAB.

I will not be able to fix it for

• Neuroscan CNT
• Any MEG system (no knowledge whatsoever and unfortunately not a lot of time to invest)

@jasmainak is this what you meant by basing the PR off your #106? It's the first time I'm doing something like this.

My steps:

• git remote add mainak https://github.com/jasmainak/mne-bids
• git fetch mainak
• git checkout -b mainak/refactor_raw_to_bids
• git pull --rebase mainak refactor_raw_to_bids
• git push --set-upstream origin mainak/refactor_raw_to_bids
• ... and then I opened this PR, in which I will work on the EEG units

I think I will be able to easily get all of Mainak's updates by periodically using git pull mainak refactor_raw_to_bids ... potentially with a --rebase flag ... so that's nice. What I don't like is that I couldn't choose my own name for this branch

Please correct me if that was wrong.

@sappelhoff I had something simpler in mind. All you needed to do was:

$ git fetch mainak refactor_raw_to_bids:refactor_raw_to_bids
$ git checkout -b channel_units

And yep, if you need to update your branch, you would just do:

$ git checkout refactor_raw_to_bids
$ git pull mainak refactor_raw_to_bids
$ git checkout channel_units
$ git rebase refactor_raw_to_bids

you could probably also do:

$ git checkout channel_units
$ git pull --rebase mainak refactor_raw_to_bids

awesome, thanks @jasmainak! ... this is much better and I got it now :-)

you only missed a step after $ git fetch mainak refactor_raw_to_bids:refactor_raw_to_bids, I think:

$ git checkout refactor_raw_to_bids

so that I check out your changes and branch off them, instead of branching off the branch from where I fetched your refactor_raw_to_bids branch.

Oh yes you are right!
