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

 13:     Sample Usage:
 14: $      typedef struct {
 15: $         PetscInt     height;
 16: $         PetscScalar  root;
 17: $         PetscReal    byebye;
 18: $      } MyParameters;
 19: $
 20: $      PetscBag     bag;
 21: $      MyParameters *params;
 22: $      
 23: $      PetscBagCreate(PETSC_COMM_WORLD,sizeof(MyParameters),&bag);
 24: $      PetscBagGetData(bag,(void **)&params);
 25: $      PetscBagSetName(bag,"MyParameters");
 26: $      PetscBagRegisterInt(bag,&params.height,22,"height","Height of the water tower");
 27: $
