  (Text, Stimmen).
- **Formulare  und :** Für die Erstellung von Umfragen
  und deren Auswahlmöglichkeiten.
- **Views:**
    - : Zeigt alle für den Benutzer relevanten Umfragen an.
    - : Ermöglicht Head Coaches das Erstellen neuer Umfragen
      (inkl. Fehlerbehebung bei der Formularinitialisierung).
    - : Zeigt Details einer Umfrage an und ermöglicht die
      Stimmabgabe.
    - : Zeigt die Ergebnisse einer Umfrage an.
    - : Funktion für die Stimmabgabe.
- **Templates:** Spezifische Templates für alle Umfrage-Views.
