See the other email, in the thread with subject line "additional
comments". The question is: can we ignore RS all the time?

I removed json-tokens from the specification and public interface.
json-generator stay around obviously because otherwise it would not be
a json stream reader.

I added a test for a naive case that reads a record:

Left as an exercise to the reader, anyway, it only concerns the implementation.
Here is another bug that went through the test suite:

Here is pull-request for easy read:
