	CircleDistCost (const double &x, const double &y)
template<typename T >
bool	operator() (const T *const sample, T *residual) const
	One formulation of a residual function for error relative to the center of a circle. Presented to the solver as three size-1 double parameters.
template<typename T >
bool	operator() (const T *const x_sample, const T *const y_sample, const T *const r_sqrt_sample, T *residual) const
	An alternative formulation of a residual function for error relative to the center of a circle. Here, the inputs (x, y, r_sqrt) are provided as separate parameters. This is mathematically identical to the previous version, but the number and size of the parameters are presented differently to the solver (one size-3 double parameter).
