We are using the default serialization process which acts recursively, i.e. serializes each field (be it primitive or reference) inside it (except static and transient).
Line 222, of src/processing/BoardState.java, which is inside BoardState (a serializable class), contains instances of ObjectComparator (which is marked as serializable right now)
Hence, ObjectComparator in src/processing/ObjectComparator.java needs to be marked as serializable as well.
