TINKERPOP-1639 Support simple String operations
https://issues.apache.org/jira/browse/TINKERPOP-1639
Added support for simple String operations. `CountLocalStep`,
`RangeLocalStep` and `TailLocalStep` can now imitate `String::length()` and
`String::substring()`.
A few examples:
```
gremlin> g.V().values("name").count(local)
==>5
==>5
==>3
==>4
==>6
==>5
gremlin> g.V().values("name").limit(local, 3)
==>mar
==>vad
==>lop
==>jos
==>rip
==>pet
gremlin> g.V().values("name").tail(local, 4)
==>arko
==>adas
==>lop
==>josh
==>pple
==>eter
gremlin> g.V().values("name").group().by(range(local, 1, 2)).next()
==>a=[marko, vadas]
==>e=[peter]
==>i=[ripple]
==>o=[lop, josh]
```
