Removing the modelManager.py file that snuck in somehow...
Added more documentation and comments.

TODO for the file upload_name in spittalbase.py was fixed on the server side.
TODO for a top-level login removed. It is unneeded. Each subclass should have it's own login method
     so that they can be used independantly. No global login is needed.
Added basic logging functionality.

Now we can more easily debug from the front-end.
