Feature/delivered reads plot

Firstly, this pull requests includes preliminary plots for _delivered_ base pairs on the /production page.

However, secondly, more greatly, it contains a lot of restructuring of the code as some first steps to make it more manageable, and hopefully more understandable.

A `setup.py` has been included, and some handlers and functions have been moved to python submodules. A directory for the runtime environment which includes static files and design files have been added. This is where a settings file should be placed, and from where the server should be started.

Thirdly, the production related plots have been moved to server side generation, and some general refactoring of the the production statistics have been made. Several not needed handlers have been removed.

Visually, here are the before and after pictures of the production page:

The trouble with overlapping years have also been fixed.
