Changing center coordinates

The Core does not contain functionality. Therefore, if you change the center coordinates, you have to update the distance and bearing of the cache from the center location. This is typically how it is done:

            Core.CenterLocation.SetLocation(lat, lon);
            Core.Geocaches.BeginUpdate();
            foreach (Framework.Data.Geocache gc in Core.Geocaches)
            {
                Utils.Calculus.SetDistanceAndAngleGeocacheFromLocation(gc, Core.CenterLocation);
            }
            Core.Geocaches.EndUpdate();
