   IMPORTANT: TinkerPop recommends creating the `TraversalSource` once and re-using it as necessary in your application.
   
  
positive.code: The console automatically performs the static imports for these methods, so they do not need to be imported again

  In the "modern" graph, calling `groupAround` with "1" as the `vertexId` argument, should return a `Map` with two keys:
  "knows" and "created", where the "knows" key should have vertices "2" and "4" and the "created" key should have
  vertex "3". As you are a good developer, you know to write a unit test to validate this outcome.  You write your
  test, compile your application, and execute your test only to find it failing on the "knows" key, which only has one
  vertex associated to it instead of two.

  As you have the Gremlin Console open you decide to debug the problem there.  You copy your Gremlin code from
  
negative.code: link:http://groups.google.com/group/gremlin-users[Gremlin Users mailing list] about a traversal that you are having
  trouble with in your application, try to convert the gist of it to one of the toy graphs.  Taking this step will make it
  easier for advanced Gremlin users to help you, which should lead to a faster response time for your problem. In
  addition, there is the added benefit that the mailing list post will be more relevant to other users, as it is
  not written solely in the context of your domain.
