com.hp.hpl.jena.sparql.engine.optimizer.StatsMatcher
Stats format:
```
(stats (meta ...) ((S P O) weight) ( weight) )
```
where S, P, O is a URI, variable, literal or one of the words ANY (matches anything), VAR (matches a variable), TERM (matches a fixed URI, or literal), URI, BNODE, LITERAL (matches one of these types).
