-//~ A stopwatch is a class designed to measure the amount of time elapsed from a particular time

-//~ Calling start starts the timer running, and calling stop stops it.
-//~ A call to reset resets the stopwatch to zero.
-//~ A stopwatch can also also used to record split times or lap times.
-//~ The elapsed time since the last start is available through the elapsed function.
-//~ When the freeze function is called while the watch is running, the elapsed time is frozen,
-//~ allowing the elapsed time to that point to be read using the frozen function,
-//~ but the watch mechanism continues running to record total elapsed time.
