Subject: Long live QCborStreamWriter!

CBOR is the Concise Binary Object Representation, a very compact form of
binary data encoding that is compatible with JSON. It was created by the
IETF Constrained RESTful Environments (CoRE) WG[1] and has since been
used in many new RFCs by that group, especially COSE[2], and is meant to
be used alongside CoAP[3].

This API is a very simple, thin wrapper around TinyCBOR[4].

See RFC 7049 <http://tools.ietf.org/html/rfc7049>.
