[vtkusers] Algorithm base class question

[Amy Squillacote]

Hi Benjamin,

You could create a vtkPointSetAlgorithm and override its 
FillInputPortInformation method so that it takes a vtkMultiBlockDataSet 
rather than a vtkPointSetAlgorithm. Take a look at how this method is 
overridden in VTK/Graphics/vtkThreshold.cxx.
