UI for viewing and editing (collections of) GeoLocations.
Viewing and editing (collections of) GeoLocations should be done using a map, ala Google Maps. Initially, all collections of GeoLocations should be shown, and the user should be able to select one of them to indicate which to manage, e.g. add and remove geo-locations. The map should center on and zoom into the selected one (or all), to make it easier to get an overview.
