public class RowLink2
extends RowLink
```
RowLink subclass which specifically contains two items (a pair).
As well as standard RowLink functionality, this object can also contain a 'score', which is an uninterpreted number. Typically this is used to record how good the match represented by a link is. This value is not taken account of in either compareTo, equals or hashCode methods.
