Usage
var v1 = new bertie.vector(100,100,100);
var v2 = new bertie.vector(-100,-100,100);
console.log(v1.dotProduct(v2)); // -0.3333333333333333
v1.flip();
console.log(JSON.stringify(v1.directions)); // [-100,-100,-100]
v1.flip();
console.log(JSON.stringify(v1.directions)); // [100,100,100]
console.log(JSON.stringify(v1.unitVector())); // [-0.5773502691896257,-0.5773502691896257,-0.5773502691896257]
console.log(JSON.stringify(v1.angleBetween(v2))); // 1.0471975511965979
console.log(v1.getLength()); // 173.20508075688772
v1.add(v2);
console.log(JSON.stringify(v1.directions)); // [0,0,200]
v2.rotateX(Math.PI/2);
console.log(JSON.stringify(v2.directions)); // [-100,-100,-100]
