Echo JS 0.11.0

This looks pretty sweet. And better than the alternatives in some ways.

Alternatives include:
- http://goessner.net/articles/JsonPath/ (like x-path for json)
- https://github.com/jcrosby/jsonquery
- http://jsonselect.org/#overview

I've used some of those before, I think json-path - but it's been a while..
