* std_unique_ptr.i
*
* The typemaps here allow handling functions returning std::unique_ptr<>,
* which is the most common use of this type. If you have functions taking it
* as parameter, these typemaps can't be used for them and you need to do
* something else (e.g. use shared_ptr<> which SWIG supports fully).
* SWIG library file for handling std::unique_ptr.
* Memory ownership is passed from the std::unique_ptr C++ layer to the proxy
* class when returning a std::unique_ptr from a function.
* Memory ownership is passed from the proxy class to the std::unique_ptr in the
* C++ layer when passed as a parameter to a wrapped function.
