Publishing notes

To develop and test, see the "Developer Installation" in the README.

Notes:

setup.py uses setuptools-markdown which requires having installed:
```
brew install pandoc
pip3 install setuptools-markdown
```

Make sure your ~/.pypirc points to correct credentials. E.g.

index-servers =
  pypitodbotdotcom

[pypitodbotdotcom]
username=todbotdotcom
password=....

To publish:

Edit setup.py to bump version
Update README.md (use pydoc blink1.blink1.Blink1 > api.txt to generate new API ref)
Check changes into git
Publish to PyPI with:

python3 setup.py sdist upload -r pypitodbotdotcom

Verify new version on PyPi: https://pypi.org/project/blink1/
