** BandInfoTable:
**
** Purpose:
** Used to index in arrays. Called by LSP sub vector

**
** Table Structure:
** The unquantized LSP vector, quantized LSP vector, and residual
** LSP error vector are each divided into three subvectors.
** The table format is as follows:
**
** 1st pair corresponds to subvector 0
** 2nd pair corresponds to subvector 1
** 3rd pair corresponds to subvector 2
**
** The 1st slot in each pair is used to index the location of
** the vector in a 10-element array. For example, for subvector
** 1, dimensions [0,..,2] get automatically mapped to array
** location [3,..,5], and for subvector 3, dimensions
** [0,..,3] automatically get mapped to array location [6,..,9].
**
** The 2nd slot in each pair corresponds to the dimension of
** the subvector
