Configure OAuth 2.0 Authentication for REST

Demonstrates Rest.SetAuthOAuth2, which associates an OAuth2 provider containing a valid access token so Chilkat adds the bearer token to the Authorization header.

Background. OAuth 2.0 bearer-token authentication attaches the access token to each request. The token is typically obtained separately through an OAuth 2.0 authorization flow before being assigned to the provider.
