This handler uses the Google API library to unshare a Google Calendar that has been previously shared. Using a Service Account Email and the corresponding P12 file (see below for details about obtaining these values) to authenticate the handler against Google's API. A call is then made to exchange the Calendar Name for a unique Calendar Id. Then another call will be made to Google to find the ACL Id of the calendar (the rule that says who the calendar can be shared to) so that it can then be deleted. Any errors that occur during the posting process will be caught and re-raised by this handler.
