Review IETF JSON Path draft

[mmccool]

The JSON Path group is working on a spec in the context of IETF, we should review it and file issues, and (of course...) reference it and align our spec with it. The repo is here: https://github.com/ietf-wg-jsonpath/draft-ietf-jsonpath-jsonpath

I also already filed an issue about JSON Pointers related to my geolocation proposal, and this issue description also includes a general introduction to the WoT Discovery work: ietf-wg-jsonpath/draft-ietf-jsonpath-base#55

See issue #234 and issue #387.
Generally we should consolidate and get caught up on our feedback regarding JSON Path, then close these more generic issues and open more specific ones after reviewing the current state of the JSONPath proposed spec from IETF.

Closing, will take up discussion in #234
