Uses the DELETE method to delete data. The data used in this example is at Chilkat Firebase Pigs Database, and is shown here:

# Uses the DELETE method to delete a Firebase record.

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# This example assumes a JWT authentication token, if required, has been previously obtained.
# See Get Firebase Access Token from JSON Service Account Private Key for sample code.

# Load the previously obtained Firebase access token into a string.
