Vec4D multiply(Number a) Vec4D multiply(Vec4D a)
	Multiplys the vector with a.

Number norm()
	Returns the vector norm of the r,g,b and a components.

Vec4D copy()
	Creates a copy of the vector.

void set(Number r, Number g, Number b, Number a)
	Sets the values of the vector all at once.

Vec4D sub(Vec4D)
	Substracts the vector a.
