Changed ControlNet::GetPoints to use iterators

  }

  //! Return QList of ControlPoints ordered by point ID

  //! Return QList of all the ControlPoints in the network

  QList< ControlPoint * > ControlNet::GetPoints() {

    QList< ControlPoint * > orderedPoints;

    QList< ControlPoint * > pointsList;

    for (int i = 0; i < pointIds->size(); i++) {

      orderedPoints.append( points->value( pointIds->at(i) ) );

    QHash< QString, ControlPoint * >::const_iterator pointsIt = points->constBegin();

    while(pointsIt != points->constEnd()) {

      pointsList.append( pointsIt.value() );

      ++pointsIt;

    }

    return orderedPoints;
