William S Fulton 71cd6a38fe Performance optimisation for directors for classes passed by value
The directorin typemaps in the director methods now use std::move on the
input parameter when copying the object from the stack to the heap prior
to the callback into the target language, thereby taking advantage of
move semantics if available.
