/**
   
   \class vtkFibersManager.
   
   This class provides a full set of rendering and interactions with so-called
   fibers, which are nothing else than VTK poly-lines stored in a vtkPolyData.
   It takes as input a vtkPolyData (the actual lines) and a vtkRenderWindowInteractor
   and does everything for the user.
   
   Different modes of rendering the lines are possible:
   - Polylines (SetRenderingModeToPolyLines()): the default mode;
   - Ribbons (SetRenderingModeToRibbons()): renders each line as a flat ribbon;
   - Tubes (SetRenderingModeToTubes()): renders each line as a tube;
   
   Note that when using the ribbon or tube mode, a vtkMaskPolyData is also used
   to lower the number of fibers depending on the maximum number of fibers allowed
   (default is 20000 - change it with SetMaximumNumberOfFibers() ).
   
   Different type of interactions are possible. By default, a cropping box
   (vtkBoxWidget) is used to limit the fibers that go through it.
