Xarray trouble

[ColCarroll]

This stops travis-sphinx from deploying docs until we can figure out what the error is.

Maintainers can deploy manually using

git pull origin master
cd doc
make html
ghp-import -p -n -f -r git@github.com:arviz-devs/arviz.git _build/html/

This is equivalent to what travis-sphinx is doing.

How did you test docs deploy in your own fork? If I learn how I can help troubleshoot this as well. Autodeploy docs are really nice

[ColCarroll]

Yeah, agree it is very nice. I went to travis and enabled builds on my fork. I did not enable the travis-sphinx deploy there (it requires an additional key), so I have to check the travis logs.

Note that this change keeps building the docs, so we can keep an eye on if they fix themselves, it just won't deploy the docs.
