// 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.
//  6/30/97     helena      Added tests for CollationElementIterator::setText, getOffset
//                          setOffset and DecompositionIterator::getOffset, setOffset.  
//                          DecompositionIterator is made public so add class scope
//                          testing.
//  02/10/98    damiba      Added test for compare(UnicodeString&, UnicodeString&, int32_t)
