The directorin typemaps will now generate a temporary variable
(specified after the type), such as:
%typemap(directorin) MyType (MyType *temp) { ... use temp ... }
The shared_ptr director typemaps have been fixed for use in functions
that take more than one parameter.
Modify the Python and Ruby director shared_ptr typemaps to be language neutral.
Port the director modifications to other scripting languages that
have shared_ptr support - Octave, R and Scilab. Scilab shared_ptr
support is not fully working and needs work though.
