Restructure Docs
Changes in Readme
I fixed some broken links, e.g.: the mpi4py link and one link the a code section on git were broken)
Changes in the generated docs
- how to generate the docs was stated twice (user/installation and dev/index) and once the dependencies were incomplete
- IMHO installation for developers should be part of dev-section (to keep it ease to find the installation guide I put in a link from installation to dec/index
- plotting, mpi4py, etc are also used by non developers, so I moved the section to the user installation
Further suggestions
- moving the section on installation of mpi4py and matplotlib in the README file as well
- installation guide for astropy, h5py (or a link), in order to keep it the way we do it for other opt. dependencies
- putting in or changing the developer section to the way most of us install nifty etc. (cloning repo, pip install --user -e .,) since also new group members use these instructions. (I think this would decrease some overhead)
