New Python update slithers into release

Behold, the new, faster version 3.7, with nanosecond timing, data classes and docs in more (human) languages

Version 3.7 of anything probably doesn't seem that notable, but stick with us here because Python 3.7, released on June 27th, 2018, is the programming language's first big update in 18 months and adds plenty of new features."
