*讨论
* 本PKZIP“通缩”的过程中使用了几个哈夫曼树。越
*共源的值由短比特序列表示。
*
*每个代码树存储在ZIP文件以压缩形式
*这是本身的长度的霍夫曼编码
*所有的代码串（按升序排列按来源值）。
*实际代码串从长度重构
*解压缩过程中，如在“应用指南”中描述
*（APPNOTE.TXT）分布情况的PKWARE的PKZIP的计划的一部分。-* trees.c by Jean-loup Gailly
*
* This is a new version of im_ctree.c originally written by Richard B. Wales
* for the defunct implosion method.
*
* PURPOSE
*
* Encode various sets of source values using variable-length
* binary code trees.
*
* DISCUSSION
*
* The PKZIP deflation process uses several Huffman trees. The more
* common source values are represented by shorter bit sequences.
*
* Each code tree is stored in the ZIP file 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 the lengths in
* the UNZIP process, as described in the application note
* (APPNOTE.TXT) distributed as part of PKWARE s PKZIP program.
