Member ug::DocuGen::CppGenerator::generate_class_public_members (): Not really implemented yet. Are there even any public members registered?
Member ug::DocuGen::CppGenerator::generate_return_value (const bridge::ExportedFunctionBase &method): Implement handling of multiple return values. Currently they are displayed as '()'. This might be superfluous if there are no methods with more than one return value registered.
