+probe_coords.py - Zeigt die Y-Koordinaten von Labels und Werten auf der
+Info-Seite, um koordinatenbasiertes Parsen zu ermoeglichen.
+
+Idee (vom Nutzer): Jeder Wert gehoert zu dem Label, UNTER dem er steht und
+UEBER dem naechsten Label. Types-Werte liegen zwischen 'TYPES OF BUSINESSES'
+und 'BACKGROUND'; Background-Werte zwischen 'BACKGROUND' und 'TOTAL PURCHASE'.
