Add more code stubs

Place most new functions into separate file server_funcs.py

Move some comments from server.py to server_funcs.py

Resolves #5

Note: This is just a suggestion in order clarify how to progress further. I mostly translated my bash-script thinking into python so if anything looks weird or if there are suggestions for improvement go ahead and add them in :)
