# As Claudio (GOOGLE Developer) mentioned in http://youtu.be/zJVCKvXtHtE?t=12m18s,
# we need to use some logic (client library) to sort your crendentials for reusing.
# Other wise on every execution of 'quickstart.py', you need human interaction for getting credentials
#
# I added 6 lines to google's 'quickstart.py' to keep authorization code for future use.
# So as long as the user has not revoked the access granted initially to the application, 
# this script don't need a human interaction. (https://developers.google.com/accounts/docs/OAuth2InstalledApp#refresh)
