  -Unlike Standard and Session OpProcessors, the Traversal OpProcessor does not simply return the results of the
  -`Traversal`. It instead returns a representation of the `Traverser` objects and any side-effects produced by the
  -`Traversal` itself.

  +to send an alias pair with key of "g" and value of "g1" and thus allow the script to refer to "g1" simply as "g".

  +When using "gather" it is important to note the metadata that is returned on the `ResponseMessage`. It returns both the
  +"sideEffectKey" that was requested as well as a value keyed as "aggregateTo". The "aggregateTo" field describes how the
  +streamed side-effect data should be treated on the client. It provides a hint as to whether or not the data should be
  +rolled back up into a single object or simply left as-is. There are four values for "aggregateTo": `bulkset`, `list`,
  +`map` and `none`.

positive.code: Traversal OpProcessor
  ^^^^^^^^^^^^^^^^^^^^^
  
  Both the Standard and Session OpProcessors allow for Gremlin scripts to be submitted to the server. The Traversal
  OpProcessor however allows Gremlin `Bytecode` to be submitted to the server. Supporting this OpProcessor makes it
  possible to submit a `Traversal` directly to Gremlin Server allowing
  link:http://tinkerpop.apache.org/docs/current/tutorials/gremlin-language-variants/[Gremlin Language Variants] to
  directly submit a `Traversal` in the native language of the GLV without having to use a script in a different language.
