* ALGORITHM
*
- * The "deflation" process uses several Huffman trees. The more
- * common source values are represented by shorter bit sequences.

- * Each code tree is stored in a compressed form which is itself
- * a Huffman encoding of the lengths of all the code strings (in
- * ascending order by source values). The actual code strings are
- * reconstructed from the lengths in the inflate process, as described
- * in the deflate specification.
