Public Member Functions
	Vec ()
	Default constructor. All elements will be initialized to zero.
	Vec (const T &s)
	Constructs a vector from a scalar number.
template<class T2>
	Vec (const Vec< N, T2 > &rhs)
	Constructs a vector from another vector of the same dimension/size.
template<class T2, size_t M>
	Vec (const Vec< M, T2 > &rhs)
	Constructs a vector from another vector of the same dimension/size.
template<class T2>
	Vec (const T2 *rhs)
	Constructs a vector from an array of values.
thisclass &	operator= (const thisclass &rhs)

	Compound subtraction with another vector.
thisclass &	operator*= (const thisclass &v)
	Compound component-wise multiplication with another vector.
thisclass &	operator/= (const thisclass &v)
	Compound component-wise division with another vector.
template<class T2>
thisclass &	operator*= (T2 s)
	Compound vector-scalar multiplication.
template<class T2>
thisclass &	operator/= (T2 s)
	Compound vector-scalar division.
thisclass	operator+ (const thisclass &v) const
