Currently VertexCombiner is expected to return a single message combining the input messages, or null in case no message should be sent. The new expected interface should return an Iterable<M>, possibly empty. The number of elements in the returned Iterable is supposed to be smaller than the number of input messages, by the initial definition of a Combiner (defined as a function to reduce I/O by combining multiple messages into 1).
