      7:      PetscBag - PETSc object that manages a collection of user data including parameters.
      8:            A bag is essentially a C struct with serialization (you can save it and load it from files).

     12:     Sample Usage:
     13: $      typedef struct {
     14: $         PetscInt     height;
     15: $         PetscScalar  root;

     17: $      } MyParameters;
     18: $
     19: $      PetscBag     bag;
     20: $      MyParameters *params;

     22: $      PetscBagCreate(PETSC_COMM_WORLD,sizeof(MyParameters),&bag);
     23: $      PetscBagGetData(bag,(void **)&params);
     24: $      PetscBagSetName(bag,"MyParameters");
