## Bulk API

The bulk API allows a client to add/update/delete mutliple verticies and/or edges within a single request.  This request will be treated as an atomic transaction in that all operations within the bulk request will either fail or succeed together.

This is often useful when attempting to add an entire subgraph.  The following example shows how a client could create 2 verticies (pserver and vserver) and link them with an edge.
