class DseGraphUnionedRDD[R] extends UnionRDD[R]

An extension of UnionRDD which automatically assigns a partitioner based on the way DseGraph stores and partitions vertex information. The graphLabels should map 1 to 1 with the RDDs provided in sequence. This ordering is used to develop a mapping between labels and the RDDs which represent the data for that label.
