(** {1 New Proof sessions ("Refectoire")} *)


(** {2 upper level structure of sessions}

   A [session] contains a collection of files, a [file] contains a
collection of theories, a [theory] contains a collection of goals. The
structure of goals remain abstract, each goal being identified by
unique identifiers of type [proofNodeId]
