[vtkusers] visualizing slice contours via vtkAppendPolyData - retry

[Malcolm Drummond]

Hi Dean

Have you used the SetNumberOfInputs method, also have you set
UserManagedInputs to On? Otherwise you need to use the AddInput method.

If you have a lot of inputs and/or don't know how many appends you'll need
to do, it might be a better idea to maintain just two inputs - one for
accumulated data and one for new data. Manually update and then transfer the
output back to the accumulated input, ready for the next append.
