   * Removed old/dead serialise/deserialze methods on *LISTIZED classes.
   * Total rewrite of DENORM to better encapsulate operation and make
     for potential to extract features from images.
-  * Thread-safety! Moved all critical globals and statics to members of the appropriate class. Tesseract is now thread-safe (multiple instances can be used in parallel in multiple threads.) with the minor exception that some control parameters are still global and affect all threads.

   * Added Cube, a new recognizer for Arabic. Cube can also be used in combination with normal Tesseract for other languages with an improvement in accuracy at the cost of (much) lower speed. *There is no training module for Cube yet.*
   * `OcrEngineMode` in `Init` replaces `AccuracyVSpeed` to control cube.
   * Greatly improved segmentation search with consequent accuracy and speed improvements, especially for Chinese.
