See the following code snippet that demonstates how to use this library.

$a = new Point($x1, $y1);
$b = new Point($x2, $y2);
$c = new Point($x3, $y3, $z3); # Infinite dimensions supported by some distance types

$distanceType = new Euclidean();
$distanceType = new EuclideanSquare();
$distanceType = new Haversine();	# For GPS coordinates (latitude and longitude)

$distance = (new Distance())
		->type(new Euclidean())	# Type is optional, and defaults to Euclidean distance
		->from($a)
		->to($b)
		->get();
