Migrate to python3

[gabriel-tessier]

As python 2.7 is supported until January 2020
https://pythonclock.org/

May think about moving the code to python 3.x

Made the branch python3 but didn't start yet!

Good thing you remind me @gabriel-tessier! I was working on this for quite a while and I need to clean a few things before giving you this version. Checkout branch python36

I think this version is stable and may go live. If you have time pls check and let me know if you find anything.

Cheers.

Maybe better to go with a minimal 3.7 support not with 3.x as some version already reach end of life.

For information about versions end of life:
https://devguide.python.org/#status-of-python-branches

Other resources about new stuff in 3.7 version
https://docs.python.org/3/whatsnew/3.7.html

Or 3.8 so we can use := as explain in this pep
https://www.python.org/dev/peps/pep-0572/

3.6 is also ok!!! : ) still have one year to live.

Good point, I'll check with Python 3.7... since python 3.6 is reaching the end of life
