Functions
template<typename VISITOR , typename... ARGS>
Status	iceberg::VisitTypeInline (const Type &type, VISITOR *visitor, ARGS &&... args)

template<typename VISITOR , typename... ARGS>
auto	iceberg::VisitType (const Type &type, VISITOR &&visitor, ARGS &&... args) -> decltype(std::forward< VISITOR >(visitor)(type, args...))
	Call visitor with the corresponding concrete type class.
template<typename VISITOR , typename... ARGS>
Status	iceberg::VisitTypeIdInline (TypeId id, VISITOR *visitor, ARGS &&... args)
	Calls visitor with a nullptr of the corresponding concrete type class.
template<typename VISITOR , typename... ARGS>
auto	iceberg::VisitTypeCategory (const Type &type, VISITOR *visitor, ARGS &&... args)
	Visit a type using a categorical visitor pattern.
