Checklist

Provide proof that this works (this makes reviews move faster). Please perform one or more of the following:

• [x] Include a screenshot showing what the graph looked like before and after your changes.

If you are changing a node or relationship:

• [x] Update the schema and readme.

If you are implementing a new intel module:

• [x] Use the NodeSchema data model.
• [x] Confirm that the linter actually passes (submitting a PR where the linter fails shows reviewers that you did not test your code and will delay your review).
