/// Transforms the deprecated `std::auto_ptr` into the C++11 `std::unique_ptr`.
///
/// Note that both the `std::auto_ptr` type and the transfer of ownership are
/// transformed. `std::auto_ptr` provides two ways to transfer the ownership,
/// the copy-constructor and the assignment operator. Unlike most classes these
/// operations do not 'copy' the resource but they 'steal' it.
/// `std::unique_ptr` uses move semantics instead, which makes the intent of
/// transferring the resource explicit. This difference between the two smart
/// pointers requires wrapping the copy-ctor and assign-operator with
/// `std::move()`.
///
/// For example, given:
///
/// \code
/// std::auto_ptr<int> i, j;
/// i = j;
/// \endcode
///
/// This code is transformed to:
///
/// \code
/// std::unique_ptr<in> i, j;
/// i = std::move(j);
/// \endcode
