I have updated this proof-of-concept API stub to include a parallel POST
way to do a sync simple cone search, and a UWS API.  The UWS API has the
most substantial possible changes from the existing XML API, since it's
heavily influenced by using JSON rather than XML and using REST verbs.
The UWS API here is designed to be generic, similar to the existing UWS
API.

This is all the work I was planning on doing in advance of our next
meeting, but let me know if anyone has any questions or problems using the
repository, or if anything is obviously missing.
