MAT[SEQ/MPI]AIJXXXX
PetscObjectBaseTypeCompare() strips off the XXXX and compares
PetscObjectTypeCompare() compares the entire string
As discussed with Richard recently for likely a similar need we also need
a
PetscObjectRootTypeCompare() that strips out the Seq/MPI for the
comparison, see MatRegisterRootname()
If you want a check for either SeqAIJ or MPIAIJ you can use
PetscObjectBaseTypeCompareAny() with MATSeqAIJ and MatMPIAIJ
