+   * \brief Controls the time-related properties of the time stepper, according to the
+   *        given input world time geomtry.
+   *
+   * A TimeNavigationController takes a TimeGeometry as input world time geometry
+   * and sets the properties of the associated stepper (BaseController).
+   * The time-related properties are:
+   *  - steps: the number of input time steps
+   *  - pos: the current time step / position of the stepper
+   *  - range: the time bounds for the slider (minimum, maximum)
+   *
+   * The timestep controls the selection of a specific time point from the TimeGeometry.
+   * The TimeNavigationController generates ITK events to tell observers,
+   * like a BaseRenderer, when the selected timestep changes.
+   *
+   * Example:
+   * \code
+   * // Initialize the time navigation controller.
+   * timeCtrl = mitk::TimeNavigationController::New();
+   *
+   * // Set the required input world time geomtry (a TimeGeometry::ConstPointer).
+   * timeCtrl->SetInputWorldTimeGeometry(geometry.GetPointer());
+   *
+   * // Set the time-related properties and send the information to the connected renderer(s).
+   * timeCtrl->Update();
+   * \endcode
+   *
+   * Vvisible navigation widgets can be connected to a TimeNavigationController, e.g., a
+   * QmitkSliceNavigationWidget (for Qt):
+   *
+   * \code
+   * // Create the visible navigation widget (a slider with a spin-box).
+   * QmitkSliceNavigationWidget* navigationWidget = new QmitkSliceNavigationWidget(parent);
+   *
+   * // Connect the navigation widget to the time-stepper of the
+   * // TimeNavigationController. For initialization (timestep, minimal and
+   * // maximal values) the values of the TimeNavigationController are used.
+   * // Thus, accessing methods of a navigation widget is normally not necessary,
+   * // since everything can be set via the (Qt-independent) TimeNavigationController.
+   * // The QmitkStepperAdapter converts the Qt-signals to Qt-independent
+   * // itk-events.
+   * new QmitkStepperAdapter(navigationWidget, timeCtrl->GetSlice());
