  Typemaps for std::wstring and const std::wstring&

  These are mapped to a Java String and are passed around by value.
  Warning: Unicode / multibyte characters are handled differently on different 
  OSs so the std::wstring typemaps may not always work as intended. Therefore 
  a #define is required to use them.

  To use non-const std::wstring references use the following %apply.  Note 
  that they are passed by value.
  %apply const std::wstring & {std::wstring &};
