Human API Webservice

[Murkantilism]

Notes

• Frontend already exists
• See additional notes in Trello here

Acceptance Criteria

• Create a NodeJS webservice that can:
  • Send a request to Human API with the user's Firebase authentication credentials (unique ID & email) to get an access token back
  • Save that token & associated human API id for the user to our database (see update_user)
  • Collect data on a recurring basis (every 6 hours? Every 12?)
