[vtkusers] Filter to change vtkDataArray name?

[Cory Quammen]

Is there a filter that will change the name of a particular data array
in a vtkDataSet?

I'll explain my need. I am using vtkImplicitModeller to compute
distances of points from a surface. I'd like to use these distance
scalars in vtkArrayCalculator, but the vtkDataSet produced by
vtkImplicitModeller does not have a name. So far I haven't been able
to figure out how to access these scalars in vtkArrayCalculator. If I
modify vtkImplicitModeller.cxx to set the name of the output scalars,
I can use it in the calculator with no problem.

Thanks in advance for the help,
Cory
