I now made it optional to use autosummary and the extra file generation
with a switch in the command line.
autodoc file generation for each module!
> -------------------------------------------------------
>
> The most important change I made, and which I would like to have
> integrated in the official software is to the autodoc.py. When the software
> is generating rst-files automatically all modules of one package get one
> rst file and so in my use case only one web page, which is nearly
> unreadable. So I added the option to generate one file for each module and
> only have an auto-summary of the modules.
> I also preferred having an auto-summary of the sub packages instead of a
> toctree, but this could be made optional or discussed. :)
>
> Further improvement could be also one file per class, but maybe that is to
> detailed.
