documentation for vorbis encoder

OOPS!
I just realised I posted links to Opus documentation and you want Vorbis. Some of it is relevant (e.g. Pyramid Vector Quantization) but a lot of it is different and reflects the lessons learned in Vorbis development (e.g. Opus/CELT explicitly encodes the band energy, Vorbis indirectly reflects this by the noise curve) and specifics relating to speech coding and low latency that Vorbis doesn't have to worry about.
