#include <Vector2.hpp>

Public Member Functions
	Vector2 ()
	Default constructor.

	Vector2 (double a, double b)

void	Zero ()
	Set both x and y values to zero.

bool	isZero () const
	Returns true if both x and y values are zero.

double	Length () const
	Returns the length of the vector.

double	LengthSq () const
	Returns the squared length of the vector (thereby avoiding sqrt).

void	Normalize ()
	Normalizes the vector.

double	Dot (const Vector2 &v2) const
	Returns the dot product of the vector.

int	Sign (const Vector2 &v2) const
	Returns positive if v2 is clockwise of this vector, negative if anticlockwise (assuming y-axis is pointing down and x-axis is pointing right).

Vector2	Perp () const
	Returns the vector that is perpendicular to this vector.

void	Truncate (double max)

double	Distance (const Vector2 &v2) const

double	DistanceSq (const Vector2 &v2) const

void	Reflect (const Vector2 &norm)

Vector2	GetReverse () const

const Vector2 &	operator+= (const Vector2 &rhs)

const Vector2 &	operator-= (const Vector2 &rhs)

const Vector2 &	*operator=** (const double &rhs)

const Vector2 &	operator/= (const double &rhs)

bool	operator== (const Vector2 &rhs) const

bool	operator!= (const Vector2 &rhs) const
