DOC: Design docs aren't being built properly

[wesm]

@jorisvandenbossche the automated docs builds here don't have the requisite Python packages to run the IPython directives, it seems. We can revert to manual builds if necessary...

The new url (with moved org and renamed repo) works for me: https://pandas-dev.github.io/pandas2/, but for some reason the redirects do not ..

Wes, I wanted to try solve this, but, I can't find the design doc sources anymore in the current repo .. ? (or I looked really bad :-)) Has this something to do with the folding in of pandas codebase?

[wesm]

Odd, I'll take a look! I'm due to spend some time working on the design docs soon anyhow

[jorisvandenbossche]

They are still at https://github.com/pydata/pandas-design (and in the history of this repo as well). I am not sure if they have been adaptations since your initial PR (#1)

One of the difficulties of having merged the design docs with the actual pandas code repo, is that I set-up travis to build / upload the docs automatically. But now the original pandas docs are included in this repo instead of the design docs, and travis is used to run actual tests.

I wanted to get the design docs fixed because I link to them in the pandas-website PR.
