[v9r3] Add documentation
About LogSE, Sandbox store, and create an index.html that makes sense.
@zmathe would you please check that what is in the Certification
folder still makes sense ?
@fstagni I have the feeling that the dev
folder could be trashed
I will try to understand as well why we have no index generated (https://lhcb-dirac.readthedocs.io/en/latest/genindex.html vs https://dirac.readthedocs.io/en/latest/genindex.html), and I would like that we also get proper code documentation. I will take care of this little by little
