//  This example requires the Chilkat API to have been previously unlocked.

//  This example uses a previously obtained access token having permission for the 
//  scope "https://www.googleapis.com/auth/cloud-platform"

//  In this example, Get Google Cloud Storage OAuth2 Access Token, 
//  the service account access token was saved to a text file.  This example fetches the access token from the file..
