added: support for UTF-8 (files utf8.h utf8.cpp)
they can be even used without the rest library
as only a library for converting between wide characters and UTF-8
changed: everywhere we use std::wstring instead of std::string
changed: Generator and Functions are templates now
they take a stream type
renamed: Info to FunInfo and it is a template too
taking a stream type
now you can use other kind of streams with the library
previous was only std::ostringstream
