TODO:

• [ ] Functionality is as advertised. Though the app declares requesting ACCESS_FINE_LOCATION, this is not accessed automatically, nor when browsing the map – but only when told by the user to use the current location, which is very good. Unfortunately, it cannot be toggled off again without killing the app – which a future release will hopefully fix.
• [x] Button Styling
• [x] implement 'Strassenverkehr'
• [ ] make a usable ui
