Summarize access to an organization's repositories on GitHub.

Run a query like this on the GitHub explorer:
https://developer.github.com/v4/explorer/

{
  organization(login: "your-org") {
    name
    repositories(first: 100) {
      edges {
        node {
          name
          collaborators(first: 100) {
            edges {
              permission
              node {
                login
              }
            }
          }
        }
      }
    }
  }
}

Then save the results in organization.json.
