;; ============================================================
;; SSG_ID - Eindeutige ID-Verwaltung fuer SSG_LIB Bloecke
;;
;; Jedes eingefuegte Element erhaelt ein Attribut "ID" mit
;; einer eindeutigen, vierstelligen Nummer (z.B. "0001").
;;
;; Befehle:
;;   IDGENERATE - Weist dem zuletzt eingefuegten Block eine neue ID zu
;;   IDSCHECK   - Prueft alle Bloecke auf doppelte IDs und korrigiert sie
;;
;; Funktionen:
;;   (ssg-id-max)             - Hoechste ID in der Zeichnung ermitteln
;;   (ssg-id-generate ent)    - Neue ID erzeugen und auf Block setzen
;;   (ssg-id-check-all)       - Doubletten pruefen und korrigieren
;;   (ssg-id-format n)        - Zahl als 4-stelligen String formatieren
;; ============================================================
