In cityFinals you should call exceptionGeneratorrunCourse If

In cityFinals() you should call exceptionGenerator.runCourse(). If no exception is thrown, print out \"No exception thrown\". If the call to runCourse() resulted in a checked exception, print out \"Caught checked exception\". If runCourse() resulted in an unchecked exception, print out \"Caught unchecked exception\".

In mountMidoriyama() you will handle the results of the grand finale. If the throwChecked parameter is true, your code should raise a RopeClimbException. If the throwUnchecked parameter is true instead, your code should raise a TimeException. If both parameters are false, nothing else needs to be done.
