This is a first commit introducing general readthedocs wiki
structure.
It introduced the following main chapters:
- Overview (is a symlink to the README.md), the readthedocs
parses the markdown from here and creates the overview page
- Architecture overview (with the sources taken from the git wiki)
- Unit-tests (with the sources taken from the git wiki)
- Troubleshooting Overview (now only memory leaks)
- Glossary (doesn't have much information for now)
