Remove map extent change from update, this will happen on setLocation if a location object is passed. Add fitBounds to _createMap, this sets a world view.
Allow Location View to be called with null location object, or partially defined location object.
Update map to view world when location object is null.
Update to allow null location object to be passed in. Add a location object to an anonymous object that is fired on location change.
Update tests to work with the new location object being passed.
