-//1.Import
-//
-//Als Teil des Entwicklungsteams sollen Sie einen Import für neue Nutzer der jeweiligen Kunden entwickeln.
-//Die Kunden schicken zu diesem Zweck CSV-Dateien mit den Daten von neuen Nutzern.
-//Diese Daten müssen in die bestehenden Datentabellen eingespielt werden.
-//Dafür sind folgende Anforderungen formuliert:
-//
-//	• Ein Sachbearbeiter ruft eine Konsolen-App auf, in welcher er die Datei und die
-//	    Kundennummer des Kunden als Parameter übergibt: Die Beispieldatei hat den Namen "import_yutani.csv" und
-//	    gehört zum Kunden mit der Nummer "K2-002"
-//
-//	• Die Datei hat den Aufbau:
-//      - Ein Nutzer mit Anrede, Vorname, Nachname und Geburtsdatum
-//      - Ggf. Adresse: Straße mit Hausnummer, PLZ, Stadt
-//      - Ggf. E-Mail
-//      - Ggf. eine oder mehrere Telefonnummern: Vorwahl ohne führende 0 und Nummer
-//
-//    	• Ein Nutzer darf für einen Kunden nicht mehrmals importiert werden.
-//
-//    	• Die Daten sollen wie folgt validiert werden:
-//    		○ Geburtsdatum: TT.MM.JJJJ
-//    		○ Valide E-Mail-Adresse
-//    		○ PLZ: exakt 5 Nummern
-//    		○ Telefonnummer 3 bis 5 Nummern für die Vorwahl und 4 bis 10 Nummern für die Hauptnummer. Keine Sonderzeichen
-//
-//	• Nicht valide Datensätze von Nutzern sollen in einem Protokoll erfasst werden, ebenso bereits vorhandene Nutzer.
-//	  Der komplette Datensatz eines Nutzers darf dann nicht importiert werden
