[vtkusers] Naming DataArray in DataSet for ParaView compliance

[Bryn Lloyd]

Hi Jerome,

I came to the same conclusion (but got no response) in January:

http://www.vtk.org/pipermail/vtkusers/2009-January/099248.html

The filters

  - vtkImageGaussianSource
  - vtkImageReslice and inherited classes

need to give their arrays a default name or use the name of the input array.

Cheers
Bryn
