Functions
template<typename Function >
BracketResult	MathUtils::BracketRoot (Function &theFunc, double theA, double theB, int theMaxIter=50)
	Bracket a root by expanding interval until sign change is found. Starting from [theA, theB], expands outward using golden ratio.
double	MathUtils::detail::Limited (double theValue, const MinBracketOptions &theOptions)
template<typename Function >
bool	MathUtils::detail::LimitAndMayBeSwap (Function &theFunc, const MinBracketOptions &theOptions, const double theA, double &theB, double &theFB, double &theC, double &theFC)
template<typename Function >
MinBracketResult	MathUtils::BracketMinimum (Function &theFunc, double theA, double theB, const MinBracketOptions &theOptions=MinBracketOptions())
	Bracket a minimum by finding three points a < b < c with f(b) < f(a) and f(b) < f(c). Uses golden section expansion with parabolic interpolation.
template<typename Function >
MinBracketResult	MathUtils::BracketMinimum (Function &theFunc, double theA, double theB, int theMaxIter)
	Backward-compatible convenience overload with only max-iterations argument.
