By the way, the __init__ method is not included on the documentation page. Something that should be changed?

Replying to @fredrik-johansson:

I believe what you want is

.. automethod:: __init__

See the "private functions" subsection of http://doc.sagemath.org/html/en/developer/coding_basics.html#documentation-strings.

Personally I try to put such documentation at the class level.

Branch LGTM, so if you don't want to fiddle with the documentation, you can set this to a positive review (once you set the author name).
