usage

var butiran = require("butiran");
var Vect3 = butiran.Vect3();

var a = new Vect3(3, 4, 0);
console.log(a);
console.log("a = " + a.strval());

var b = new Vect3(4, -3, 0);
console.log("b = " + b.strval());

var c = Vect3.cross(a, b);
console.log("a x b = " + c.strval());

var d = Vect3.dot(a, b);
console.log("a . b = " + d);

Vect3 { x: 3, y: 4, z: 0 }
a = (3, 4, 0)
b = (4, -3, 0)
a x b = (0, 0, -25)
a . b = 0
