  * Created by: Helena Shih
  *
  * Modification History:
  *
  *  Date        Name        Description
  *  2/5/97      aliu        Modified createDefault to load collation data from
  *                          binary files when possible.  Added related methods
  *                          createCollationFromFile, chopLocale, createPathName.
  *  2/11/97     aliu        Added methods addToCache, findInCache, which implement
  *                          a Collation cache.  Modified createDefault to look in
  *                          cache first, and also to store newly created Collation
  *                          objects in the cache.  Modified to not use gLocPath.
  *  2/12/97     aliu        Modified to create objects from RuleBasedCollator cache.
  *                          Moved cache out of Collation class.
  *  2/13/97     aliu        Moved several methods out of this class and into
  *                          RuleBasedCollator, with modifications.  Modified
  *                          createDefault() to call new RuleBasedCollator(Locale&)
  *                          constructor.  General clean up and documentation.
  *  2/20/97     helena      Added clone, operator==, operator!=, operator=, and copy
  *                          constructor.
  * 05/06/97     helena      Added memory allocation error detection.
  * 05/08/97     helena      Added createInstance().
  *  6/20/97     helena      Java class name change.
  * 04/23/99     stephen     Removed EDecompositionMode, merged with
  *                          Normalizer::EMode
  * 11/23/9      srl         Inlining of some critical functions
  * 01/29/01     synwee      Modified into a C++ wrapper calling C APIs (ucol.h)

     // return a valid collation object, if the system is functioning properly.
