EFNav Integration

[Rain336]

Since this year, EF got a really nice navigation software based on c3nav that I honestly prefer over the map display currently in the App. So I would suggest replacing the current map with an integration into efnav, by displaying it inside a web view. Besides displaying a point of interest the c3nav (and by extend the efnav most likely too) supports displaying your current position, but this is currently not easy to integrate into our App (it would require injecting javascript into the web view and keeping the web view open so the position stays accurate). The position is also located using either Bluetooth Low Energy beacons and/or Wifi, which might have to be set up by EF themselves.
