* Modification history :
*
* Date        Name        Description
* 02/01/01    synwee      Added normalization quickcheck enum and method.
* 02/12/01    synwee      Commented out quickcheck util api has been approved
*                         Added private method for doing FCD checks
* 02/23/01    synwee      Modified quickcheck and checkFCE to run through 
*                         string for codepoints < 0x300 for the normalization 
*                         mode NFC.
* 05/25/01+   Markus Scherer total rewrite, implement all normalization here
*                         instead of just wrappers around normlzr.cpp,
*                         load unorm.dat, support Unicode 3.1 with
*                         supplementary code points, etc.
* 2009-nov..2010-jan  Markus Scherer  total rewrite, new Normalizer2 API & code
