Local Subgraph Adaptor
The local subgraph adaptor takes an existing Distributed Graph and filters out all of the nonlocal edges and vertices, presenting only the local portion of the distributed graph to the user. The behavior is equivalent to (and implemented with) a filtered graph, and is a noncopying view into the graph itself. Changes made through the filtered graph will be reflected in the original graph and vice-versa.

Reference
The local subgraph adaptor adapts and forwards all operations of distributed graphs, the signatures of which will be omitted. Only operations unique to the local subgraph adaptor are presented.
Member Functions
