-------------------------------------------
spmallette opened a new pull request #968: TINKERPOP-2078 Added ReferenceGraph
URL: https://github.com/apache/tinkerpop/pull/968
https://issues.apache.org/jira/browse/TINKERPOP-2078
Basically replaces `EmptyGraph.instance().withRemote()` for
`ReferenceGraph.open().withRemote()` which is a bit more intuitive.
```text
gremlin> graph = ReferenceGraph.open()
==>referencegraph[reference]
gremlin> g = graph.traversal().withRemote('conf/remote-graph.properties')
==>graphtraversalsource[referencegraph[reference], standard]
gremlin> g.addV('person').property('name','stephen')
==>v[16]
gremlin> g.V().valueMap()

> ReferenceGraph rather than EmptyGraph or RemoteGraph
> ----------------------------------------------------
>
> Key: TINKERPOP-2078
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2078
> Project: TinkerPop
> Issue Type: Improvement
> Components: structure
> Affects Versions: 3.3.4
> Reporter: stephen mallette
> Assignee: stephen mallette
> Priority: Major
>
> {{RemoteGraph}} was long ago deprecated for {{withRemote()}} typically
> spawned from {{EmptyGraph}} which is weird. Create {{ReferenceGraph}} which
> sets up some 4.x concepts (given current thinking). For GLVs, make sure
> {{EmptyGraph}} didn't leak into them and deal with those issues as needed.
> Update all docs to stop using {{EmptyGraph}}.
