Public Member Functions
double	delay () const
	Returns the time passed between the call of start() and this member function. Works also if the timer is not stopped. Returned time is expressed in seconds.
void	print () const
	Prints the time passed between the call of start() and this member function. Works also if the timer is not stopped. Printed time is expressed in seconds.
void	setCaption (const std::string &caption)
	Sets the caption of the timer.
void	start ()
	Starts the timer.
void	stop ()
	Stops the timer.
void	stopAndPrint ()
	Stops the timer and prints the time passed between the call of start() and this member function. Printed time is expressed in seconds.
	Timer (bool _start=true)
	Creates a timer with the caption "Timer". If the given boolean is true, the timer starts.
	Timer (const char *caption, bool _start=true)
	Creates a timer with the given caption. If the given boolean is true, the timer starts.
	Timer (const std::string &caption, bool _start=true)
	Creates a timer with the given caption. If the given boolean is true, the timer starts.

Detailed Description

The Timer class allows to instantiate simple Timer objects that can be used everywhere.

When a Timer object is create, by default the timer starts (you can change this option using the bool argument of the Timer constructor). To each timer can be associated a caption, and the printed/returned values are expressed in seconds.
