"Suggest edit" button link is broken #336
Description
When you click the "Suggest edit" button on the rendered version, it gives a 404 error. On inspection, it was found that "notebooks/" was added to the link twice, and removing one of them fixes the link. The same problem also seems to be causing trouble while loading the notebooks on Binder. Binder loads the notebooks, but there is an error message once loaded.
The problem could be due to the _config.yml file having path_to_book having the value "notebooks", but you have also included "notebooks/" to the paths in the _toc.yml.
