Patch for Hoda Amer

Browse source 
Core: 
         In completeParseASTFactory.getExpressionResultType(): Added  the support 
         for expression types: PM_DOTSTAR, PM_ARROWSTAR, CONDITIONALEXPRESSION
 Tests: 
         Added more success test cases to CompleteParseASTExpressionTest 
         and more failure test cases to FailedCompleteParseASTExpressionTest 
         in testing PM_DOTSTAR, PM_ARROWSTAR, CONDITIONALEXPRESSION

Added more success test cases to CompleteParseASTExpressionTest
and more failure test cases to FailedCompleteParseASTExpressionTest
in testing PM_DOTSTAR, PM_ARROWSTAR, CONDITIONALEXPRESSION
2003-09-16 Andrew Niefer
- modified resources/search/classDecl.cpp & include.h to include some operators
- added testOperators_bug43063_bug42979() to MethodDeclarationPatternTests
