V3d represents a three dimension vector with Float coordinates x, y and z.

V3d has the following operators overloaded:

Addition: a + b given a and b of V3d type.
Substraction: a - b given a and b of V3d type.
Negation: -a given a of V3d type.
Scalar multiplication: a * n given n of type Float or Int
Scalar division: a / n given n of type Float
