"""Tests fuer die Staubereiche in tro_annotate.py (--anlage, --read-jams).

Kleine Anlage: ein Kreisel mit zwei TROs hintereinander (K0042). Die Bloecke
JAM_AREA tragen Name, Foerderer, Nummer und den stabilen Schluessel TRO +
Eingang; --read-jams uebernimmt im Dialog JAM_EDIT geaenderte Nummern nach
<csv>_jam_names.ini, und scl_context setzt sie in die SCL ein.
