After some struggle to understand OAuth2 and Google Calendar API, I
managed to insert a calendar entry.
Now, I want to be able to manipulate the calendar, without the user
being logged on, in their browser - which is "offline" access according
to the Google docs [1] (I'm not sure whether this is an OAuth2 feature,
or a Google API feature).
I noticed that the ZnGoogleOAuth2Session is coded for "online" access.
Should I start coding a ZnGoogleOAuth2OfflineSession - is this the right
approach? What's the best way to contribute the code - just make changes
in Zinc-SSO-OAuth2-Core package, for later merging?
