Requesting additional examples for adding nodes and edges

[DavidAnDavis2021]

The workbook for https://github.com/gchq/gaffer-docker/blob/develop/docker/gremlin-gaffer/gremlin-gaffer-modern-example.ipynb contains useful examples for using the Tinkerpop utility with Gaffer's Accumulo integration.

Would it be possible to add examples for adding new nodes and edges to the graph?

Currently when I try the standard Gremlin Tinkerpop commands to add a node I get missing ID errors and would find it very helpful to see an example for how to do this in Gaffer.

While it's not listed under the limitations of the current Tinkerpop implementation, I have a feeling this may not be fully working yet.

@t92549 - could you confirm the status of adding elements?
