Gekko 0.6 released

[Henry151]

@mark.sch I've summarized everything in a doc file, see here: https://github.com/askmike/gekko/blob/pr...per_api.md

@Henry151 I fixed this ~40 minutes ago, see here: https://github.com/askmike/gekko/commit/...d45fcbbcbe are you running the latest commit on that branch?

Thanks, latest commit, no problem. However I think Binance is down right now, so I'm getting "Error:

Gekko tried to retrieve data since 2018-06-26 03:31:00, however
        binance did not return any trades."

But I think that's just a binance problem, not a gekko problem.

I compiled node from source to enable static probe points so that I can use bcc-tools assorted node-observing tools to watch what the program is doing "under-the-hood" to try to learn more about how it works. Very excited to see what I can learn! Unfortunately i don't know how much i'll understand, but the whole process has been fascinating.
