   PetscOps: structure of core operations that all PETSc objects support.

      getcomm()         - Gets the object's communicator.
      view()            - Is the routine for viewing the entire PETSc object; for
                          example, MatView() is the general matrix viewing routine.
                          This is used by PetscObjectView((PetscObject)obj) to allow
                          viewing any PETSc object.
      destroy()         - Is the routine for destroying the entire PETSc object;
                          for example,MatDestroy() is the general matrix
                          destruction routine.
                          This is used by PetscObjectDestroy((PetscObject*)&obj) to allow
                          destroying any PETSc object.
      compose()         - Associates a PETSc object with another PETSc object with a name
      query()           - Returns a different PETSc object that has been associated
                          with the first object using a name.
      composefunction() - Attaches an a function to a PETSc object with a name.
      queryfunction()   - Requests a registered function that has been attached to a PETSc object.

   PetscObjectStateIncrease - Increases the state of any PetscObject,

   Synopsis:
   #include "petscsys.h"
   PetscErrorCode PetscObjectStateIncrease(PetscObject obj)

   Not Collective

   Input Parameter:
.  obj - any PETSc object, for example a Vec, Mat or KSP. This must be
         cast with a (PetscObject), for example,
         PetscObjectStateIncrease((PetscObject)mat);

   Notes: object state is an integer which gets increased every time
   the object is changed. By saving and later querying the object state
   one can determine whether information about the object is still current.
   Currently, state is maintained for Vec and Mat objects.

   This routine is mostly for internal use by PETSc; a developer need only
   call it after explicit access to an object's internals. Routines such
   as VecSet() or MatScale() already call this routine. It is also called, as a
   precaution, in VecRestoreArray(), MatRestoreRow(), MatDenseRestoreArray().
