Generates docs automatically

[j8r]

The CI can generates docs, then pushing them to the gh-pages branch.
Travis CI docs: https://docs.travis-ci.com/user/deployment/pages/

If you are not a fan of giving a GITHUB_TOKEN, which I totally agree (it is like giving our GitHub password), then an other option is to add a SSH public key to the repository.
The issue is that your account will be now the committer.
I have made an image, but the script can be used directly: https://github.com/j8r/dockerfiles/tree/master/gh-pages-ci.

A third option can also be to create a new GitHub user for this.

@veelenga If it is possible to use GitHub Actions, I can do the docs automation myself (I have already done this for some other of my projects) - and no token needed.

@j8r thanks. You were right regarding GITHUB_TOKEN. I didn't want to share it, sorry. Good to know about GitHub Action.
