Public Member Functions
	GeneralCircle (const double &x_c, const double &y_c, const double &r)
	Constructor: Pass x and y-coords of centre and radius (all pinned)

	GeneralCircle (Data *geom_data_pt)
	Alternative constructor: Pass x and y-coords of centre and radius (all as part of Data)

virtual	~GeneralCircle ()
	Destructor: Clean up if necessary.

void	position (const Vector< double > &zeta, Vector< double > &r) const
	Position Vector at Lagrangian coordinate zeta.

void	position (const unsigned &t, const Vector< double > &zeta, Vector< double > &r) const
	Position Vector at Lagrangian coordinate zeta at time level t (t=0: present; t>0: previous level). Steady object, so we simply forward the call to the steady version.

double &	x_c ()
	Access function to x-coordinate of centre of circle.

double &	y_c ()
	Access function to y-coordinate of centre of circle.

double &	R ()
	Access function to radius of circle.

unsigned	ngeom_data () const
	How many items of Data does the shape of the object depend on?

Data *	geom_data_pt (const unsigned &j)
	Return pointer to the j-th Data item that the object's shape depends on.

Protected Attributes
Vector< Data * >	Geom_data_pt
	Vector of pointers to Data items that affects the object's shape.

bool	Must_clean_up
	Do I need to clean up?

Detailed Description

GeneralCircle in 2D space.

$x = X_c + R \cos(\zeta)$

$y = Y_c + R \sin(\zeta)$

The three parameters and are represented by Data and can therefore be unknowns in the problem.
