Copy your Google Sheets spreadsheet to Firebase using this AppScript.
// Installation & Setup
// 1. Create a spreadsheet.
// 2. Under Tools > Script Editor, paste this script
// 3. Under Resources > Libraries, add two library dependencies:
// - OAuth2: 1B7FSrk5Zi6L1rSxxTDgDEUsPzlukDsi4KGuTMorsTQHhGBzBkMun4iDF
// - FirebaseApp: 1hguuh4Zx72XVC1Zldm_vTtcUUKUA6iBUOoGnJUWLfqDWx5WlOJHqYkrt
// 4. Create a Firebase project and initialize the Realtime Database
// 5. Fill in your project details in FIREBASE_IO_URL and SERVICE_ACCOUNT below.
// 6. Under Resources > Cloud Platform Project, add your Firebase project's project number from GCP. You
// can find your project number in the GCP Cloud Console here: https://console.cloud.google.com/home/dashboard?project=_
// 7. Give it a whirl from your Google Sheet! Note: you may need to click past security warnings.
// TODO: Add your Firebase project ID here. It will look something like "my-project-123"
