;;; Given an SBN, produces a sexp containing the description of the
;;; functions of the SBN that Org-mode can interpret as a table.
;;; This function is therefore very similar to print-org-tbn.
;;;
;;; Like print-org-tbfs/state, if #:headers is #f, does not print the
;;; names of the inputs of the TBFs. If #:headers is #t, the output
;;; starts by a list giving the names of the variables.
;;;
;;; If #:func-names is #t, the first column of the table gives the
;;; variable which the corresponding TBF updates.
;;;
;;; If both #:func-names and #:headers are #t, the first cell of the
;;; first column contains the symbol '-.
