[Paraview] pvpython -> extracting timesteps

[Takuya OSHIMA]

Hi Pierre-Olivier,

If you look at the python examples on the wiki
http://www.paraview.org/Wiki/ParaView/Python_Scripting
you'll notice there are two notations used for the extraction of a
timestep. One is the notation you used and another is

scene.StartTime = reader.TimestepValues.GetData()[0]

at around the bottom of the page. As far as I tried only the latter
works for the cvs head. Hope someone update the wiki and clarify it...
