/*
    How to create values for a GLatLng point for "mapDestinationArray" and "targetDestinationArray":
    Go to GoogleMaps and search your location, e.g. "Balanstr. 73, 81541 München".
    Right-click on the spot you want to be the destination and choose "was ist hier?" from the pulldown.
    Find the geolocation latitude and longitude values in the search field, e.g. "48.11924,11.600593".
