[vtkusers] Display mesh with attributes

[Alex Malyushytskyy]

I would recommend to check
http://www.vtk.org/Wiki/VTK/Examples/Cxx/PolyData/ColorCells
or
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Graphs/ColorVerticesLookupTable


As for your code, at the first glance you do not have lookup table is created,
but "Setting ColorModeToMapScalars means that all scalar data will be
mapped through the lookup table."

I guess as a result color mapping does not happen.

Hope this helps,
   Alex
