* resolution to .csv & .json output (#1058)

* resolution to .csv & .json output

trogdor123 got me looking at the right section where the params were being input in json. made some minor tweaks to the code and now both are outputting correctly.

* Update darwin.js

...changes - formatting.

* darwin.js - crossover strategy (#1060)

noticed that generational output was static from gen to gen for smalen1 and smalen2. sure enough, those are coded into the strategy itself, but were left out of the darwin.js strategy config for mutation.

* docker fix

* Resolve docker build problems

* noop strategy: readme/links/list (#1062)

* Travis. Docker. (#1063)
