Demonstrates how to refresh an OAuth2 Yahoo Mail access token. CkPython

# This example requires 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 
# saved by this example: Get Yahoo Mail OAuth2 Access Token

# The access token JSON looks like this:

# {
#   "access_token": "kCVQdnOdul...LHucA--",
#   "refresh_token": "AIenVWETSo0jklFBVkPS8vVm8E.Dj9ToRG.xDbDYmZ55WIs5t6CZhDkD",
#   "expires_in": 3600,
