Public Member Functions
void	start ()
	Start time measurement.

void	stop ()
	Stop time measurement and increment add to the current diff_time summation variable. Also increment the number of times this clock has been run.

void	reset ()
	Reset the timer to 0. Does not change the timer running state but does recapture this point in time as the current start time if it is running.

float	getTime () const
	Time in sec. after start. If the stop watch is still running (i.e. there was no call to stop()) then the elapsed time is returned added to the current diff_time sum, otherwise the current summed time difference alone is returned.

void	addTime (const float dt)
	Add dt seconds of time to the counter. Does not increment the number of clock sessions.

float	getAverageTime () const
	Time in msec. for a single run based on the total number of COMPLETED runs and the total time.

Protected Attributes
struct timeval	start_time
	Start of measurement.

float	diff_time
	Time difference between the last start and stop (in ms)

float	total_time
	TOTAL time difference between starts and stops (in ms)

bool	running
	flag if the stop watch is running

int	clock_sessions
	Number of times clock has been started and stopped (for averaging)
