[Paraview] GroupParts filter

[Amy Henderson]

Hi Patrick,

This is actually the expected behavior in ParaView. The Group Parts filter 
does not merge the input data sets into a single data set, but instead 
groups the separate inputs so that a single filter can be applied to all of 
the parts at the same time. When you run the CleanUnstructuredGrid filter 
on the results of GroupParts, you are actually applying an instance of 
CleanUnstructuredGrid to each individual part. The instances of 
CleanUnstructuredGrid have no knowledge of each other, which would be 
necessary in order to merge points across datasets.

That said, this would be a feature request, not a bug. You could add it to 
the ParaView bug tracker (http://www.paraview.org/Bug/) and mark it as a 
feature request.
