xmlstarlet like functionality

[mrjcleaver]

I write this comment for people like me that might be coming from xmlstarlet and looking for something similar but for JSON.

I suspect that underscore-cli can fulfill some similar requirements. And, where there are gaps, may serve as inspiration for what else is possible.
