CppUnit - C++ port of JUnit Code

for Solaris/Forte C++ compiler.

* TODO: cleaned-up and added new things.

* include/cppunit/extensions/HelperMacros.h: CPPUNIT_TEST_SUITE now declares
a class named ThisTestFixtureFactory which is a wrapper for the fixture
factory. This removes the need to cast the fixture to the correct type when
using the factory. Updated other macros implementation to use this new
factory. Modified CPPUNIT_TEST_CUSTOM(S) macros to use this new factory
class. Added macro CPPUNIT_TEST_ADD to help create new macros like
CPPUNIT_TEST_xxx.

* examples/cppunittest/HelperMacrosTest.h:
* examples/cppunittest/HelperMacrosTest.cpp: added unit tests for
CPPUNIT_TEST_CUSTOM, CPPUNIT_TEST_CUSTOMS and CPPUNIT_TEST_ADD.
