Detailed Description

Simple free lossless/lossy audio codec Based on Paul Francis Harrison's Bonk (http://www.logarithmic.net/pfh/bonk) Written and designed by Alex Beregszaszi

TODO:

CABAC put/get_symbol
independent quantizer for channels
>2 channels support
more decorrelation types
more tap_quant tests
selectable intlist writers/readers (bonk-style, golomb, cabac)
