Feature Request

I propose to use the Sphinx extension sphinx.ext.viewcode to add the python source code to the docs and crosslink it.

This could help users understand the relations between the various levels of indirection we use. Also it could be a little help with poorly or undocumented parts of the API (we should improve the docs, but that's a long-term project).

Here is an example how this would look like (note the [source] link):

The link will guide to a page containing the source code:

Please give a short feedback on the idea. If there is a general approval, I'll submit a pull request.
