//To start the class:
	include "vcage.class.php";
	$VCAge = new VCAge();

//To validate an age:
	$VCAge->VAge(day, month, year); //BOOL returns true when valid and false when invalid

//To calculate an age:
	$VCAge->CAge(day, month, year); //INT returns the age as an integer

//To validate then calculate an age (there are 1 methods)
/*	First (this is more complex and involves more code)
	- This first checks the age is valid then echo's the age
	- On failure echo's the error
	if ($VCAge->VAge(day, month, year)) echo $VCAge->CAge(day, month, year);
	else echo $VCAge->Error;
/*	Second (This essentially does what the first method does but incorperated into the one function)
	- This incorperates the first into one step it validates then calculates the age
	- On success the age will be displayed
	- On failure the message "Invalid Age: " then the error message will be displayed
	echo $VCAge->V_CAge(day, month, year);

//Calculation will never fail unless you don't give it an integer, or number in a string
//Validation will fail on an invalid Day, Month or Year, for example 29FEB2009, or if you don't give it an integer, or number in a string
//If something fails then it will all be outputed to the Error variable, to display the error:
	echo $VCAge->Error;
