(Node.js) Firebase POST - Pushing Data (JSON Object)

Uses the POST method to append a new record (JSON Object) at a particular location in the database. Firebase automatically generates the push ID and returns it in the response. The data used in this example is at Chilkat Firebase Pigs Database, and is shown here:
