[vtkusers] deleting cells interactively from an unstructured grid

[kshivann at engineering.uiowa.edu]

hi all,
    i want to delete a cell in the unstructured grid interactively.  
solution available in the VTK mailing list is to maintain a seperate  
vtkList and copy the updated vtkList to the new unstructured grid  
being created. Is this the best possible solution and can i use the  
function RemoveReferenceToCell().

thanks
