[vtkusers] How to pick specific polylines from a polydata dataset?

   I have a vtkPolyData dataset consisting of a set of 2D
vtkPolyLines.  I want to be able to use the mouse/keyboard
to pick a subset of these polylines.
   What would be the best way to do this?

   I'm thinking that I must have a separate actor for each 
polyline, then use vtkCellPicker.  If this is the right 
approach, how do I create separate actors for each polyline?
