* @brief Class UnitTest is simple utility for running unit tests.
* It provides basic routines for tracing success or failure of tests,
* and reporting the results.
* \par Code Sample:
* \code
try {
std::cout << "Testing tstOne" << std::endl;
tstOne(&ut);
ut.passes("Test XXX passed");
} catch( ... ) {
ut.failure("An unknown exception was thrown");
}
ut.report();
return ut.NumFail();
* \endcode

* 0: Report the number of tests passed, failed, and expected failures.
* 1: Report the number of passed tests (if <=20) or the number passed
* otherwise, report all failures, report the number of expected
* failed tests (if <=50) or the number passed otherwise.
* 2: Report all passed, failed, and expected failed tests.
