[Twisted-Python] Installing Twisted on a clean Windows system

[Jeff Grimmett]

Aaaand, installed Python 3.6.6 and pip install'd Twisted 18.4.0 without any
problems.   So much for getting those sweet performance improvements in 3.7
for now - Twisted is an absolute requirement, 3.7 is not.

Anyways, looks like there's a compatibility issue between 3.7 and Twisted
on Windows at this point.  Anything I can to do assist in troublshooting,
lmk.  I'll be glad to help if I can do it.   I'm completely lost in the
woods where this kind of stuff is concerned.

Regards,

Jeff
