class	Piece<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable,M extends org.apache.hadoop.io.Writable,S> Piece that should be extended in common usecases, when we want to be: - sending and then receiving messages from vertices - sending data to be aggregated from workers to master - sending values from master, via aggregators, to workers (basically - we don't want to use WorkerContext)
