+// MPEG Layer-3 huffman decoding class.

+//  This class is derived from a CHuffmanDecoder object. In addition to
+//  the CHuffmanDecoder object, this object calculates the number of
+//  spectral lines in the big value area, the number of spectral lines in the
+//  count-one area and the region boundaries within the big value area from
+//  an MPEG Layer-3 bitstream sideinfo.
