> Control which aspects of the traverser propagate into an inner traversal by using the {{respawn}} factory method.
> {noformat}
> // Clone only the location by default.
> g.V.map(respawn().out('mother').name)
> // Clone sack and path
> g.V.as('a').map(
>   respawn(sack,path).
>   sack().as('s').select('a','s'))
> {noformat}
> We would also like to allow the inner traversal to have its own sack and side-effect scope.  This would require something that returns a {{GraphTraversalSource}}, e.g. {{respawnSource}}.  That also means that {{GraphTraversalSource}} needs a new step, e.g. {{identity}}, that would allow it to be used as an inner traversal.
> {noformat}
> // can have its own sack definition
> g.V.map(respawnSource().withSack(0.0).identity().out()...)
> {noformat}
