WRAPPER_API void ExportToSupplementaryString(const GEOCALC_NAMESPACE::CString& inString, bool loadAsCustom)
This function will export the objects to the specified string. Any objects the specified objects rely upon will also be exported. Note that the objects passed in do not have to be in the DataSource currently.
