  Système de changement de classe, par Prexus,.
   
  Caractéristiques:

    * Système de changement de classe pour chaque héros en chaque classe de la BDD
    * Système d'expérience de classe, individuels et parallèle aux niveaux (gain via combats, voir plus bas)
    * Apprentissage de compétences via niveau de classe, les niveaux étant utiles uniquement pour l'évolution des caractéristiques
    * Changements de compétences lors de changement de classe gérés
    * Interface graphique

  Pour appeler l'interface de changement de classe, utilisez
    $scene = Scene_ClassChange.new
  Pour ajouter de l'experience de classe à un personnage, utilisez
    $game_party.members[IDperso].class_gain_exp(XPgagné, IDclasse)
  ex:
    $game_party.members[0].class_gain_exp(12, 3)
    Fait gagner 12 Xp de classe à la classe 3 du perso 0
 Pour ajouter des niveaux de classe, utilisez
    $game_party.members[0].class_level_up(2)
