Public Member Functions
	BoundingBox ()
	Default constructor for ROOT compatibility. Cell weight defaults to 1.

	BoundingBox (float x1, float y1, float x2, float y2)
	Initialises the bounds of the rectangle to the given values. Automatically swaps the x or y values if they are given in a decreasing.

void	operator&= (const BoundingBox &other)
	Expands the bounding box such that it also covers the given bounding box.

void	expand (float delta)
	Expands the rectangle in each direction by the given value delta.

float	getWidth () const
	Getter for the width of the bounding box rectangle.

float	getHeight () const
	Getter for the height of the bounding box rectangle.

float	getLeft () const
	Getter for the location of the left of the bounding box rectangle (lower x bound). NAN if unset.

float	getBottom () const
	Getter for the location of the bottom of the bounding box rectangle (lower y bound). NAN if unset.

float	getRight () const
	Getter for the location of the right of the bounding box rectangle (upper x bound). NAN if unset.

float	getTop () const
	Getter for the location of the top of the bounding box rectangle (upper y bound). NAN if unset.

void	clear ()
	Clears all bounds to NAN.

Private Attributes
float	m_left
	Memory for the lower x bound of the rectangle.

float	m_bottom
	Memory for the lower y bound of the rectangle.

float	m_right
	Memory for the upper x bound of the rectangle.

float	m_top
	Memory for the upper y bound of the rectangle.
