Fix defualt serailizer 
Use streaming JSON
Since ServerMessage.write() does not accept the "callback" parameter,
here's a version that yields on every 100 writes, or if the Stream.write
returns false.

It works, and "returns" quickly, but is SLOOOWWW
Flatten JSON iteration
Cope with streams who implementaion of "write" ignores the callback
Add timing info
Yield in 8K blocks
Implement ReadableStream interface
Various attempts to make Node streaming work
Merge github.com:MatAtBread/ApiPublisher into StreamingJSON
Merge branch 'StreamingJSON' of github.com:MatAtBread/ApiPublisher into StreamingJSON
Fix streaming - not sure it's worth it though
Add timing debug for streaming
Reduce noisy debug. Fix issue when endpoint does not exist
Implement ApiPublisher.prototype.sendReturn
Allow for "text/plain" responses which are not parsed into JSON but
simply returned to the callee asynchronously as strings.
