[Paraview] No TimeSteps attribute for XdmfReader in pv 3.8.0 on mac os x 10.6

[Utkarsh Ayachit]

To change the requested time-step, you need to use the following API:

> probe.UpdatePipeline ( 1.0 ) # argument is the time value for the timestep you're interested in.

If you do not know the time values, the reader has a property named
TimestepValues which is the list of timesteps provided by the reader
that you can access after calling reader.UpdatePipelineInformation().
