[Mne_analysis] Problem including reference electrode in info['chs'][.]['loc']

[Eric Larson]

Hey Emily,

It's probably best to use e.g. DropBox if you can so other devs not at
Martinos can also have a look. But please, as usual, make sure your data
are appropriately anonymized first before sharing.

I'll also email you privately so we can try to iterate on this a bit, and
report back to the email list what we figure out.

Eric
