[vtkusers] Accessing streamer array in vtkStreamer

[Avan Suinesiaputra]

I want to make a tracer particle animation over a streamline.
First I put spheres in my streamline's start positions.
Then I animate the spheres using a vtkStreamArray's object to track
position of each sphere in a specified time.
Do you know a method to do that without vtkStreamArray.
I created the processing in C++ and it works good.
