If the viewer format is <A HREF="../Viewer/PetscViewerFormat.html#PetscViewerFormat">PETSC_VIEWER_ASCII_MATLAB</A> then the information is printed after a % symbol
so that MATLAB will treat it as a comment.
<P>
If the viewer format is PETSC_VIEWER_ASCII_VTK*, <A HREF="../Viewer/PetscViewerFormat.html#PetscViewerFormat">PETSC_VIEWER_ASCII_LATEX</A>, or
<A HREF="../Viewer/PetscViewerFormat.html#PetscViewerFormat">PETSC_VIEWER_ASCII_MATRIXMARKET</A> then don't print header information
as these formats can't process it.
<P>
Developer Note: The flag donotPetscObjectPrintClassNamePrefixType is useful to prevent double printing of the information when recursion is used
to actually print the object.
