[Paraview] Writing IntegrateAttributes to CSV using Python

If there's no Servers/Filters/vtkAttributeDataToTableFilter.h and
Servers/Filters/vtkAttributeDataToTableFilter.cxx then I am guessing
you are not updating correctly. There may be some sticky tags set with
your CVS checkout. Can you look at
ParaView3/VTK/Utilities/kwsys/kwsysDataStamp.cmake and verify that the
date mentioned is indeed today's?
