negative.code: The methods `Graph.v()` and `Graph.e()` are default methods in Graph and can be overridden as desired if a more optimal retrieval is possible.
  
  IMPORTANT: The MyGraph implementation of V() and E() are linear scans. In many situations, indices can be leveraged in situations such as `g.V().has('name','dan')`. In order to "fold" the has()-step into MyGraphStep, a <<traversalstrategy,`TraversalStrategy`>> is required. Please review TinkerGraph's `TinkerGraphStepStrategy` and `TinkerGraphStep` for the fundamentals.
  
  Finally, note that `Element` objects can be "traversed off of." That is, it is possible to `v.outE()` and `e.inV()`, etc. The method that implemented is `Vertex.start()` and a `MyVertex` implementation is demonstrated below.
  
  [source,java]
  public GraphTraversal<Vertex, Vertex> start() {
      final GraphTraversal<Vertex, Vertex> traversal = new DefaultGraphTraversal<Vertex, Vertex>(this.graph);
      return (GraphTraversal) traversal.addStep(new StartStep<>(traversal, this));
  }
  
  `MyVertex.start()` is required by `ElementTraversal<A>` interface and a default implementation is defined in `VertexTraversal<Vertex>`. As such, the above `start()` declaration is not required, though ultimately extensions to the method will be desired especially when OLAP concepts are taken into account.
  
  [source,java]
  public default GraphTraversal<A, A> start() {
      final GraphTraversal<A, A> traversal = GraphTraversal.of();
      return traversal.addStep(new StartStep<>(traversal, this));
  }
