This at the moment:
public SpanFeatureGenerator(String prefix, Object finder, int
prevWindowSize, int nextWindowSize) {
System.out.println(prefix);
System.out.println((String)finder);
System.out.println(prevWindowSize);
System.out.println(nextWindowSize);
System.exit(1);
}
It is obviously a test to understand if my generator is called.
