------------------
* Add metrics, i.e., model-size independent test outcomes to almost all test
cases.
* Repair auto generation of API docs and update section on test suite.
* Remove our dependecy on PyGithub and TravisPy by reimplementing all the
necessary steps with `requests`
* Add unit and integration tests for `runner.py` and `reports.py`, except
for `memote online`.
* Debug `memote online` - could only be tested manually, CI is impossible
without a secure way of storing github credentials.
* Add logging statements to all CLI functions to facilitate future debugging.
