swig/Lib/typemaps/swigmove.swg
William S Fulton dad7c93ca0 Provide SWIGTYPE MOVE typemaps in swigmove.i
For implementing full move semantics when passing parameters by value.
Based on SWIGTYPE && and std::unique_ptr typemaps which implement move
semantics.

Added for all languages, but untested for: Go, Ocaml, R, Scilab (and
unlikely to be fully functional for same reasons as for std::unique_ptr
support).
