VTK data object validity checker
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
It would be useful to have an external means of determining the validity of a vtkDataSet-derived object (e.g. does the length of the point data array match the number of points, do the point ids described in cells correspond to valid points). There are a lot of external VTK dataset writers in the wild, and this feature would allow us to sanity check a dataset before it crashes somewhere else in the guts of a pipeline.
