Example for 3.1.x

Hi!

You [example](https://github.com/rmuller/infomas-asl/tree/release-3.1#example-usage-31x-versions) don't work. Instead `.collect(AnnotationDetector::getType);` and `.collect(AnnotationDetector::getMethod);` need use  `.collect(Cursor::getType);` and `.collect(Cursor::getMethod);` respectively.

Best regards
