/*! @file codebooks.h
*
* @brief Declaration of routines for the inverse component transform and permutation.
* The collection of codebooks that are used by the decoder are called a codeset.
* The codebook in seach codeset is derived from the master codebook that is
* included in the codec by including the table for the codebook. The encoder
* uses specialized codebooks for coefficient magnitudes and runs of zeros that
* are derived from the master codebook.
* @version 1.0.0
