[vtkusers] Using vtkMarchingCubes3D with vtkContourWidget

[Karthik Krishnan]

Jonathan:

Use the other signature of the method GetNextCell. [ int
GetNextCell(vtkIdList *pts) ]That should be wrapped...

The code to re-order the points based on the connectivity information
would be written in java as :

  vtkIdList idlist = new vtkIdList();
  unorderedPolyData.GetLines().GetNextCell(idlist);
  npts = idlist.GetNumberOfIds();
  for ( int i = 0;  i < ( npts-1 );  i ++)
    {
    points.InsertPoint(i, unorderedPolyData.GetPoints().GetPoint(pts[i]));
    }
