TINKERPOP-1642 Pushed integrateChild() operations into Parameters.set() There was no need to continually iterate the traversal list and doing integrateChild() over and over again for each newly added traversal. Removing those wasteful cycles and only doing that once, when the Traversal was added helped improve performance.
