template<class T> struct hash<std::experimental::shared_ptr<T>>;		(library fundamentals TS)

The template specialization of std::hash for std::experimental::shared_ptr<T> allows users to obtain hashes of objects of type std::experimental::shared_ptr<T>.

For a given std::experimental::shared_ptr<T> p, this specialization ensures that std::hash<std::experimental::shared_ptr<T>>()(p) == std::hash<T*>()(p.get()).
