Description

Should use LocalMessageScope to access edges rather than assuming it has full access to the star-graph around a vertex which may not be the case for partitioned vertices.

For instance, g.E will execute v.outE on all vertices. Rather, it should send messages on inE.

In general, TraversalVertexProgram should only send global messages when it absolutely has to (e.g. jumping) in order to be optimizable by the executing GraphComputer which currently cannot make any assumption about the execution and always has to retrieve the entire star-graph which may be inefficient.
