This is strictly for upserting a couple of Vertices or Edges.
If you want to upsert many Vertices or Edges in bulk, we will cover that in
the next code snippet.

We can essentially upsert as many vertices or edges as we want, and then when we are ready,

We can do many more vertex attribute operations using the FieldValue class.
