[vtk-developers] No api for vtkAlgorithm::SetInputData()

[Utkarsh Ayachit]

I just pushed a topic to gerrit that addresses this issue:
http://review.source.kitware.com/#/t/1267

Also, I've added extra logic to SetInputDataObject(...) to ensure that
the algorithm is not changed unless the data object has changed.
