positive.code: inspire you to new levels of usage. While a use case may not fit your needs, you may well find it worthwhile to
  read, as it is possible that a "feature" will be discussed that may be useful to you.
  
  The following points summarize the key features discussed of each use case:
  
  * <<learning-tool,A Learning Tool>>
  ** Introducing the <<toy-graphs,toy graphs>>
  
negative.code: The console automatically performs the static imports for these methods, so they do not need to be imported again
  in that environment.

  The diagram above displays the "modern" graph for reference.  Assuming that `g` refers to a `TraversalSource` generated
  from a `Graph` instance that refers to that 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.
