[11/15] tinkerpop git commit: TINKERPOP-1862 Fix Messenger
implementations for Spark/Giraph handling BOTH
TINKERPOP-1862 Fix Messenger implementations for Spark/Giraph handling BOTH
These now behave like TinkerMessenger and in the case of BOTH pass the message to the opposite vertex in the StarGraph
