[vtkusers] COnversion to 4.2

[Charl P. Botha]

Both of your errors are related to the same fundamental change.  VTK
doesn't include possibly unnecessary headers anymore in order to speed
building.  This means that if you make use of a class, you have to make
sure that YOU include its header.

Make sure that your code explicitly includes both vtkUnstructuredGrid.h
and vtkDataSet.h.

Same problem: make sure that your code (in this case cross-section.cpp)
explicitly includes "vtkPolyDataMapper.h".

Good luck,
