this is ready to merge 👍

@oesteban - i merged #1977, so let's merge that with this and then create the fix.

[oesteban]

I'm fixing the documentation building: there is some indentation error in the confounds module. Once I fix that, I'll merge master in.

[oesteban]

Ok, building the docs with docker in my desktop works fine now. Also merged with master. Let's see if Circle goes through. If so this is finally ready.
