/**
-* File tblcoll.cpp
-*
-* Created by: Helena Shih
-*
-* Modification History:
-*
-* Date Name Description
-* 2/5/97 aliu Added streamIn and streamOut methods. Added
-* constructor which reads RuleBasedCollator object from
-* a binary file. Added writeToFile method which streams
-* RuleBasedCollator out to a binary file. The streamIn
-* and streamOut methods use istream and ostream objects
-* in binary mode.
-* 2/11/97 aliu Moved declarations out of for loop initializer.
-* Added Mac compatibility #ifdef for ios::nocreate.
-* 2/12/97 aliu Modified to use TableCollationData sub-object to
-* hold invariant data.
-* 2/13/97 aliu Moved several methods into this class from Collation.
-* Added a private RuleBasedCollator(Locale&) constructor,
-* to be used by Collator::getInstance(). General
-* clean up. Made use of UErrorCode variables consistent.
-* 2/20/97 helena Added clone, operator==, operator!=, operator=, and copy
-* constructor and getDynamicClassID.
-* 3/5/97 aliu Changed compaction cycle to improve performance. We
-* use the maximum allowable value which is kBlockCount.
-* Modified getRules() to load rules dynamically. Changed
-* constructFromFile() call to accomodate this (added
-* parameter to specify whether binary loading is to
-* take place).
-* 05/06/97 helena Added memory allocation error check.
-* 6/20/97 helena Java class name change.
-* 6/23/97 helena Adding comments to make code more readable.
-* 09/03/97 helena Added createCollationKeyValues().
-* 06/26/98 erm Changes for CollationKeys using byte arrays.
-* 08/10/98 erm Synched with 1.2 version of RuleBasedCollator.java
-* 04/23/99 stephen Removed EDecompositionMode, merged with
-* Normalizer::EMode
-* 06/14/99 stephen Removed kResourceBundleSuffix
-* 06/22/99 stephen Fixed logic in constructFromFile() since .ctx
-* files are no longer used.
-* 11/02/99 helena Collator performance enhancements. Special case
-* for NO_OP situations.
-* 11/17/99 srl More performance enhancements. Inlined some internal functions.
-* 12/15/99 aliu Update to support Thai collation. Move NormalizerIterator
