(** [GraphsToVerifyPPO] generates a GraphViz DOT graph which can be used
  to generate the pictorial form of the above graph. *)

(** Finally, we export the computation to OCaml so we can print it to a file,
  link it in with other code, etc.
 
The picture versions of the above graphs are shown below:
