## Description
Added NullRowTriplePatternStrategy.java to support queries in which the ?s
?p ?o are all null (unbound)
Also added this Strategy to RyaTripleContext default triple pattern
strategies, so that it is used.
### Tests
Performed an integration test, before the patch I wasn't able to perform
SELECT * { s? p? o? } queries, after the patch I can.

> Issue Type: Bug
> Environment: Accumulo 1.6.5 installed on EMR 4.6.0 (Hadoop 2.6.0)
> Reporter: Kiet Ly
> Assignee: David W. Lotts
>
> I ran this query using REST
> http://10.162.96.61:8000/web.rya/queryrdf?query=select * where { ?s ?p ?o }
> and it crashed. I just want to see the triples that I had inserted. I ran the
> query against the RYA I built from develop branch with accumulo 1.6.5.
> The error indicate this query is not supported, "select * where { ?s ?p ?o
> }".
> {code}
> java.lang.IllegalArgumentException: TriplePattern[RyaStatement{subject=null,
