    // Note: The code for setting up the Chilkat REST object and making the initial connection can be done once.

    // (It's a good idea to put the connection setup code in a separate function/subroutine.)

    // This example loads the JSON access token file 
    // saved by this example: Get Google Contacts OAuth2 Access Token
