[vtkusers] Problem with surface reconstruction and contour filter in C++.

[Andrew J. P. Maclean]

Thanks for that. I forgot about the rationalisation of the header files!
However it still doesn't fix my problem, in that the contour filter is
not returning any data.

Recent cleanups of all the vtk classes have removed #include "stuff.h"
from
many headers and you obviously haven't got a
#include "vtkImageData.h"
statement at the top of your file. Hence the compiler doesn't know it's
a
subclass of vtkDataSet. All the headers just state
class vtkImageData;
now so you need to add it. It's a pain, but it make the build process
cleaner and faster (and it;s the right thing to do really)
