/**
   \class vtkMetaSurfaceMesh vtkMetaSurfaceMesh.h "vtkMetaSurfaceMesh.h"
   \brief Concrete implementation of vtkMetaDataSet for surface mesh handling
   \author Nicolas Toussaint
   
   This class is a powerfull vtk Addon class that helps handling a vtkDataSet.
   You can use it as a tool for handling surface mesh, modify it, Add some scalars to it, etc.
   Use the Read function to read vtkPolyData format files, as well as .mesh files.
   Use the Write function to write it into a vtkPolyData format files.
   And you can associate to the metamesh a specific vtkProperty
