Generating ddox documentation

this: https://github.com/rejectedsoftware/ddox

looked cool the last time I looked at it.

I'd like to use it to generate static html and integrate it into pyd's readthedocs.

I'm thinking get travis to build the docs, upload it to s3, then have readthedocs' build download and incorporate it.

Basic build

git clone git@github.com:rejectedsoftware/ddox.git
