title: How to get the combined vertex and edge properties with gremlin and janusgraph
body: <p>I'm using JanusGraph as a graph database in my spring boot application, and I want to form a gremlin query to retrieve the properties of both - outgoing Edge and its associated Vertex. I also want the tokens(id, label etc) to be included in the properties.</p>
