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

* This example uses a previously obtained access token having permission for the 
* Google Calendar scope.

* In this example, Get Google Calendar OAuth2 Access Token, the access
* token was saved to a JSON file.  This example fetches the access token from the file..
