[Paraview] Changing Chart Series Visibilities from Python

[pat marion]

Hi Greg,

I think I found a bug, or else I don't quite understand what is happening.
It seems that under certain circumstances the python layer fails to wrap all
the properties of a proxy.  I look into this, but for now you can work
around the issue by accessing the c++ api:

 >>> p = rep.SMProxy.GetProperty("SeriesNamesInfo")

>>> series_names = [p.GetElement(i) for i in
xrange(p.GetNumberOfElements())]
