The IConverter interface (or an abstract child) should provide default implementations for these methods: `InputStream exportModelToInputStream(Model model) throws ConverterException, InconsistentModelException;` `File exportModelToFile(Model model, String filePath) throws ConverterException, InconsistentModelException, IOException;` and it (or an abstract child) should provide these methods: `File stream2file(InputStream stream);` Currently the converters implement the above methods all in their own way, which is unnecessary and can lead to inconsistent behavior depending on the input file.
