- add() will be used to add a MapLocation to the model with beginInsertRows()...endInsertRows() - clear() will be used to clear the model with beginRemoveRows()... endRemoveRows() NOTE: emiting dataChanged() does not seem to update the QML view for this model so calling being<..>Rows() seems to be the "correct Qt approach" to do this.
