How about applying greedy to SINGLETON state? I think it is illegal
combination. Also maybe change GREEDY into `QuantifierProperty`? It will
decrease the number of methods/fields.

> Greedy quantifier will try to match the token as many times as possible. For
> example, for pattern {{a b* c}} (skip till next is used) and inputs {{a b1 b2
> c}}, if the quantifier for {{b}} is greedy, it will only output {{a b1 b2 c}}.
