Public Member Functions
	GenericPolygon ()=default
	Default constructor.

	GenericPolygon (std::size_t size)
	Initializes with a know size.

template<class InputIterator>
	GenericPolygon (InputIterator first, InputIterator last)
	Initializes from a known range.

bool	is_clockwise () const
	Checks if the polygon has a clockwise orientation (right-hand rule).

void	reverse_orientation ()
	Reverses the orientation of the polygon. The first vertex (pointed to by `p.begin()`, or [0]) remains the same.

bool	contains (const Vec< 2, FT > &point) const
	Tests if a `point` lies inside the polygon.

bool	contains (const GenericPolygon< FT > &plg) const
	Tests if a polygon `plg` lies inside this polygon (i.e., all its vertices are inside).

FT	signed_area () const
	Returns the signed area of the polygon. The signed area is positive for counter clockwise polygons and negative for clockwise polygons.

FT	area () const
	Returns the area of this polygon. This is the absolute value of the signed area, so it is always positive.

GenericBox< 2, FT >	bbox () const
	Returns the smallest axis-aligned bounding box containing this polygon.

Checks if the polygon has a clockwise orientation (right-hand rule).

This method determines the orientation of a polygon based on the sign of its signed area:
