Tests:

ES6 Class
var p1 = new Point1(10, 10); var p2 = new Point1(10, -10); var sum = p1.add(p2); var dif = p1.sub(p2);
Function Prototype
var p1 = new Point2(10, 10); var p2 = new Point2(10, -10); var sum = p1.add(p2); var dif = p1.sub(p2);
Object Literal
var p1 = Point3(10, 10); var p2 = Point3(10, -10); var sum = p1.add(p2); var dif = p1.sub(p2);
Functional
var p1 = {x:10, y:10}; var p2 = {x:10, y:-10}; var sum = add(p1, p2); var dif = sub(p1, p2);
