Ajouts des fonctionnalités suivantes:
- Ajout d'une méthode comptant le nombre d'étudiants ayant validé leur année (moyenne supérieure ou
égale à 10) dans une promotion.
- Changement de la classe Grade pour qu'elle permette de stocker des notes correspondant à une absence
du résultat (affiché ABS).
- Calcul du nombre d'absents d'une promotion.
- Calcul de la note maximum et minimum (hors absence) d'une promotion.
- Calcul pondéré de la moyenne de résultats en fonction du nombre de crédits des UE.
- Calcul de la moyenne (hors absence) d'une promotion.
