Sphinx documentation generation not working

[jsbueno]

The refactoring of the project from a single Python file into a full module broke sphinx -
documentation content is partial, despite almost all classes and functions having
a good enough docstring with markup for document generation

I had to do a small research and check how the docs folder was written, but I was able to fix it.
The PR is bellow:

Is this related to the fact that images are missing from the pypi page?

no - images not showing there is another issue, completely different. Probably that has to do with the links needing to be absolute, and I am using then relative.
