/*@C
   PetscBagView - Views a bag of values as either ASCII text or a binary file

   Collective on PetscBag

   Input Parameter:
+  bag - the bag of values
-  viewer - location to view the values

   Level: beginner

   Warning: Currently PETSc bags saved in a binary file can only be read back
     in on a machine of the same architecture. Let us know when this is a problem
     and we'll fix it.
