[vtkusers] labelling iso-lines

[rashedk]

Perhaps I didnt phrase my question correctly, so there is absolutely no
simple way of displaying the iso-value of each iso-contour? 

BTW, as vtkContourFilter inherits from vtkPolyDataAlgorithm, the output
(contours) of the contourFilter is polydata, with cells that I can access
one-by-one?
