docs: python bindings
* Restructured the docs directory to account for the GNU preferred source doc format (.texi) and the Python preferred source doc format (.rst) and the real source doc format (.org). * Both the perceived source formats will need to be generated from the .org files and included at this stage. Unfortunately there is not yet a native org-to-rst transformation method in the org-mode software in Emacs nor is there a a direct means of going from reST to Org-mode from Docutils. There's only third party packages like Pandoc and, while very good, there is no guarantee of consistency; so we can't entirely automate this bit (yet).
