Script to add unassigned users to an org

It would be useful to have a script that searches a GitHub Enterprise instance for users that aren't part of an Organization, then batch invites those users to the Org.

No file, test, or entry point is named. Start by reviewing the repository's existing sample scripts and the GitHub Enterprise organization and user APIs; done should mean identifying unassigned users and batch-inviting them to the organization.
