/** @note{updated by peter karasev, 2015 to read texture coordinates + material properties}
    @note{An example of a supported (*).mtl file is show below.
             Lighting values and texture images are specified, and a corresponding vtkActor
             with properties and vtkTexture will be created upon import. }
