Typedefs
using	openswmm::findroot::NewtonFunc = std::function<void(double x, double* f, double* df)>
	Synchronous function and derivative evaluator for newton().

using	openswmm::findroot::RidderFunc = std::function<double(double x)>
	Synchronous scalar function evaluator for ridder().

Functions
int	openswmm::findroot::newton (double x1, double x2, double *rts, double xacc, const NewtonFunc &func)
	Find a root with Newton steps and a bisection fallback.

double	openswmm::findroot::ridder (double x1, double x2, double xacc, const RidderFunc &func)
	Estimate a bracketed root with derivative-free Ridder iterations.
