(** All new identifier names ougth to be created via this module. *)

(** [node_key nk name] returns a node ident that won't clash, using [name] or not. 

   The idea is the following: the caller propose a name to map the
   node key. But since that name may clash, we need to work a little bit
   more. This is the purpose of that function.
   
   nb : for a certain node key, it will always return the same string 
   (which means that [name] migth be ignored).
