{@code PartitionStrategy} partitions the vertices, edges and vertex properties of a graph into String named
partitions (i.e. buckets, subgraphs, etc.).  It blinds a {@link Traversal} from "seeing" specified areas of
the graph given the partition names assigned to {@link Builder#readPartitions(String...)}.  The traversal will
ignore all graph elements not in those "read" partitions.
