[vtkusers] vtkCellPicker capabilities

[Clinton Stimpson]

Does vtkCellPicker support picking of multiple cells?  All I see is that 
it returns the id of the closest cell and the dataset.

There is support for picking multiple vtkProps but I can't see support 
for multiple cells.

I need the ability to identify multiple cells of datasets or a dataset 
that were picked.  Any suggestions?

Thanks,
Clint
