VTU Grid Data in Separate File
Several users have requested the ability to have grid data stored in a separate file for the VTK data formats (see example discussion linked below). I took at stab at making this change for the unstructured grid format on my branch. I think it is most of the way there but the code is seg faulting. My expectation is that I am missing something in the two calls I am making to bring the point and cell elements from the separate file into the original file. (Line 167 of vtkXMLUnstructuredGridReader.cxx and Line 448 of vtkXMLUnstructuredDataReader.cxx). I have attached my test case I have been using to develop the change. What are your thoughts?
