CPPUnit Addon

I had to dig CPPUnit a little to have a possibility to inspect values of MFC CString in case of test failure.

#include <cppunit/TestAssert.h>

CPPUNIT_NS_BEGIN
// specialization for the CString type
template<>
struct assertion_traits<CString>
{
  static bool equal( const CString& x, const CString& y )
  {
    return x == y;
  } 
 
  static std::string toString( const CString& x )
  {     
    // adds quote around the string to see whitespace
    OStringStream ost; 
    ost << "\""<<(LPCSTR)x<<"\"";
    return ost.str();;
  }
};
CPPUNIT_NS_END

When I'll have enough time I'll readjust CompilerOutputter a little to have nice green and red lines in the console :)
