 The class `de.vill.main.UVLModelFactory` exposes the static method `parse(String)` which will return an instance of a `de.vill.model.FeatureModel` class. If there is something wrong, a `de.vill.exception.ParseError` is thrown. The parser tries to parse the whole model, even if there are errors. If there are multiple errors, a `de.vill.exception.ParseErrorList` is returned which contains all errors that occurred.
