Accurately determine if the user's location is out-of-view in the map #43
Description
Kujaku needs to accurately determine if the user's current location is out-of-view in the MapActivity after the map has centered on the current user location.
Currently, the target icon on the bottom-right turns blue if the user's location is in focus. The user's location has a marker. If the map is scrolled and the user's marker is no longer visible, the target icon does not turn to white.
