[vtkusers] simple 2D plotting data structure

[Jeff Lee]

Sorry, I didn't fully read about the strip-chart stuff.  Ideally, you 
want it to be threaded, and be able to append your dataset instead of 
sending a new one at every iteration.  Since vtkXYPlotActor takes 
vtkDataSet as input, you could probably insert the new cell and assign 
it the new scalar value and then update the pipeline (which should 
update the graph).  I haven't tried it, but it seems like a way to go.
