   Public Member Functions
       template<typename _Up  = _Dp, typename  = _DeleterConstraint<_Up>> constexpr unique_ptr () noexcept
           Default constructor, creates a unique_ptr that owns nothing.
       template<typename _Up , typename > unique_ptr (auto_ptr< _Up > &&__u) noexcept
       unique_ptr (const unique_ptr &)=delete
       template<typename _Up  = _Dp, typename  = _DeleterConstraint<_Up>> constexpr unique_ptr (nullptr_t)
           noexcept
           Creates a unique_ptr that owns nothing.
       template<typename _Up  = _Dp, typename  = _DeleterConstraint<_Up>> unique_ptr (pointer __p) noexcept
       unique_ptr (pointer __p, typename conditional< is_reference< deleter_type >::value, deleter_type, const
           deleter_type & >::type __d) noexcept
       unique_ptr (pointer __p, typename remove_reference< deleter_type >::type &&__d) noexcept
       unique_ptr (unique_ptr &&__u) noexcept
           Move constructor.
       template<typename _Up , typename _Ep , typename  = _Require<               __safe_conversion_up<_Up,
           _Ep>,           typename conditional<is_reference<_Dp>::value,                      is_same<_Ep,
           _Dp>,                      is_convertible<_Ep, _Dp>>::type>> unique_ptr (unique_ptr< _Up, _Ep >
           &&__u) noexcept
           Converting constructor from another type.
       ~unique_ptr () noexcept
           Destructor, invokes the deleter if the stored pointer is not null.
       pointer get () const noexcept
           Return the stored pointer.
       const deleter_type & get_deleter () const noexcept
           Return a reference to the stored deleter.
       deleter_type & get_deleter () noexcept
           Return a reference to the stored deleter.
       operator bool () const noexcept
           Return true if the stored pointer is not null.
       add_lvalue_reference< element_type >::type operator* () const
           Dereference the stored pointer.
       pointer operator-> () const noexcept
           Return the stored pointer.
       unique_ptr & operator= (const unique_ptr &)=delete
       unique_ptr & operator= (nullptr_t) noexcept
           Reset the unique_ptr to empty, invoking the deleter if necessary.
       unique_ptr & operator= (unique_ptr &&__u) noexcept
           Move assignment operator.
       template<typename _Up , typename _Ep > enable_if< __and_< __safe_conversion_up< _Up, _Ep >,
           is_assignable< deleter_type &, _Ep && > >::value, unique_ptr & >::type operator= (unique_ptr< _Up,
           _Ep > &&__u) noexcept
           Assignment from another type.
       pointer release () noexcept
           Release ownership of any stored pointer.
       void reset (pointer __p=pointer()) noexcept
           Replace the stored pointer.
       void swap (unique_ptr &__u) noexcept
           Exchange the pointer and deleter with another object.
