New extension for exporting non-public events to google Calendar

I have just published an extension we (CiviCooP) developed for Coordinatie Vluchtelingen Vrijwilligers Ede (CVVE) CVVE is facilitating the organisation of activities for refugees in Ede. Many activities are organised by willing citizens and CVVE is the bridge between those citizens and the refuees. So to keep track of everything which is going CVVE needed an export of the events in their Google Calendar.
