;;; Commentary:

;; Functions for referencing data from the header arguments of a
;; litorgical block.  The syntax of such a reference should be
;;
;;   #+VAR: variable-name file resource-id:name
;;
;; - variable-name :: the name of the variable to which the value
;;                    will be assigned
;;                    
;; - file :: path to the file containing the resource, or omitted if
;;           resource is in the current file
;;
;; - resource-id :: the id or name of the resource, or 'previous' to
;;                  grab the previous table, or 'next' to grab the
;;                  next table
;;
;; So an example of a simple src block referencing table data in the
;; same file would be
;;
;; #+var: table previous
;; #+begin_src emacs-lisp
;; (message table)
;; #+end_src
;;
