Functions
template<std::size_t I, std::size_t J, typename T, typename... PresentT, typename... GivenT>
auto	bertini::detail::GetByIndex (const std::tuple< PresentT... > &, const std::tuple< GivenT... > &absent_args) -> typename std::enable_if< I==sizeof...(PresentT), const T & >::type
	Get the value of type T, pulling from the given (absent) args when T is not among the present types.
template<std::size_t I, std::size_t J, typename T, typename... PresentT, typename... GivenT>
auto	bertini::detail::GetByIndex (const std::tuple< PresentT... > &present_args, const std::tuple< GivenT... > &) -> typename std::enable_if< I !=sizeof...(PresentT), const T & >::type
	Get the value of type T from the present args when T is among the present types (the I != sizeof... overload).
template<std::size_t...>
void	bertini::detail::ValidateTypes ()
	Proxy function ensuring the types are distinct and indexable by type (compile-time check).
template<typename... UnpermutedT, typename... PermutedPresentT>
std::tuple< const UnpermutedT &... >	bertini::Unpermute (const PermutedPresentT &... present_permuted_args)
	Reorder a set of present arguments into the declared UnpermutedT order, default-constructing any absent.
