Public Member Functions
	Point ()
	Default constructor does nothing (for performance).
	Point (double x, double y)
	Construct using coordinates.
void	set_zero ()
	Set this point to all zeros.
void	set (double x_, double y_)
	Set this point to some specified coordinates.
Point	operator- () const
	Negate this point.
void	operator+= (const Point &v)
	Add a point to this point.
void	operator-= (const Point &v)
	Subtract a point from this point.
void	operator*= (double a)
	Multiply this point by a scalar.
double	Length () const
	Get the length of this point (the norm).
double	Normalize ()
	Convert this point into a unit point. Returns the Length.

Public Attributes
double	x
