Class Description

                                                                      
 TStopwatch                                                           
                                                                      
 Stopwatch class. This class returns the real and cpu time between    
 the start and stop events.                                           
                                                                      

 Create a stopwatch and start it.

 Start the stopwatch. If reset is kTRUE reset the stopwatch before
 starting it. Use kFALSE to continue timing after a Stop() without
 resetting the stopwatch.

 Stop the stopwatch.

 Resume a stopped stopwatch. The stopwatch continues counting from the last
 Start() onwards (this is like the laptimer function).

 Return the realtime passed between the start and stop events. If the
 stopwatch was still running stop it first.

 Return the cputime passed between the start and stop events. If the
 stopwatch was still running stop it first.

 Print the real and cpu time passed between the start and stop events.
