[Paraview] MultiBlock Dataset Naming Issues

[Michael Jackson]

Ok. But wouldn't that just set the name of the multiblock dataset that  
holds all the extracted datasets? I am looking for something like:  
multiblock->SetDataName(blockNumber, Name);

And for those names to show up in the gui somewhere I guess.
