;;; Commentary:
;;
;; An Infinote session organizes its documents in a tree. Text
;; documents are the leafs of this tree, Inner nodes are called
;; directory nodes.
;;
;; Example:
;;
;; + root       (directory node)
;;   + dir1     (directory node)
;;     + doc1   (text node)
;;   + doc2     (text node)
;;
;; The corresponding class hierarchy in Rudel looks like this:
;;
;; + `rudel-infinote-node'
;;   + `rudel-infinote-node-directory'
;;   + `rudel-infinote-document'
;;     + `rudel-infinote-document-text'
