Added to typemaps: reference type in/out

Browse source 
Strings <=> std::string by value
std::wstring accessible from Ocaml.  The string example converts a multibyte
japanese EUC sequence to a single wchar_t sequence if you have the ja_JP.EUC-JP
locale, or similar.
Better handling of reference in types
Corrected problems with & * mismatch in type verifier.
Type verifier now really functional.  No more type errors in places they
wouldn't be allowed in C++, unless you work at it.
Added argout_ref example for argout_ref.
Init code now effective (called from let _ = f_<module>_init ())
