     *  Description:
     *      This class is to simulate a stopwatch for processes.  At the
     *  beginning of the program, the stopwatch must be initiated.  Then,
     *  use the startClock to start the stop watch and use the getTime to
     *  get the amount of time elapsed since the clock started.
     *  
     *  e.g.
     *  TimerSystem timer;
     *
     *  timer.startClock();
     *  cout << "Hello, World!\n";
     *  cout << "Time elapsed:  " << timer.getTime() << endl;
     *
