double	reset ()
	Resets the stopwatch.
void	start ()
	Starts the stopwatch.
double	stop ()
	Stops the stopwatch and returns total time (since last reset).
double	stop_d ()
	Stops the stopwatch and returns time since last start / read.
double	read ()
	Returns the total time without stopping the stopwatch (but resets the differential timer).
double	read_d ()
	Returns the time since last read/start without stopping the stopwatch (but resets the differential timer).

Protected Member Functions
virtual double	seconds () const
	Return the current time, to be overriden in derived classes.
Protected Member Functions inherited from stopw_base
double	adv_stopwatch ()
	Advance the stopwatch, return diff, handle single overflows.

Additional Inherited Members
Protected Attributes inherited from stopw_base
double	last_time
	The last time we read/started/stopped the clock.
double	total
	The total elapsed time since construction or reset.
const double	secs_per_tick
	Used in seconds() to convert internal time to s.
const double	overflow_secs
	If we overflow once, we miss this many seconds; We assume that internally long ints are used, i.e.
int	running
	The status.
