Add doc support and other CI related files

This change adds verious bits needed for CI and/or documentation
scraping as well as some README files.

The version in the CMake file was set to 0.1.0 in prep for activation
of CI jobs -- we want to be able to fiddle with those without actually
pushing a 1.x.x package to the repo. Once CI jobs are working we can
up the version to 1.0.0 to match the AP version.
