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

// It is assumed we previously obtained an OAuth2 access token.
// This example loads the JSON access token file 
// originally obtained by this example: Get Google People API OAuth2 Access Token
// or refreshed by this example: Refresh Google People API OAuth2 Access Token
