explain in more detail how simple enums can be used in shuffle w07

[bjornregnell]

Several students use advanced enums instead of simple in the last task of shuffle, but that was not the objective. Example of usage with extends that has not been lectured:

  enum Category(val englishName: String, val swedishName: String):
    case RoyalFlush    extends Category("royal flush",     "royal flush")
    case StraightFlush extends Category("straight flush",  "färgstege"  )
    case Fours         extends Category("four of a kind",  "fyrtal"     )
    case FullHouse     extends Category("full house",      "kåk"        )
    case Flush         extends Category("flush",           "färg"       )
    case Straight      extends Category("straight",        "stege"      )
    case Threes        extends Category("three of a kind", "tretal"     )
    case TwoPair       extends Category("two pairs",       "två par"    )
    case OnePair       extends Category("pair",            "par"        )
    case HighCard      extends Category("high card",       "högt kort"  )
    case None          extends Category("nothing",         "inget"      )

This shoud be a simple enum instead and the naming logic should be kept in another singelton:

enum Category:
  case RoyalFlush, StraightFlush, Fours, FullHouse, Flush, Straight, Threes, TwoPair, OnePair, HighCard, None

Won't fix as this is now made optional.
