7.  def thenBy(ord2: Ordering[T]): Ordering[T]

   Returns a new Ordering which compares elements using the specified Ordering if this Ordering returned 0 when comparing them.

   Returns a new Ordering which compares elements using the specified Ordering if this Ordering returned 0 when comparing them.

   This method is an alias of thenOrderingBy, intended to be used when chaining several calls in order to reduce verbosity, as in the following example:

   case class IntTuple(a: Int, b: Int, c: Int, d: Int)
   
   object IntTuple {
     val orderingA: Ordering[IntTuple] = Ordering.by(_.a)
     val orderingB: Ordering[IntTuple] = Ordering.by(_.b)
     val orderingC: Ordering[IntTuple] = Ordering.by(_.c)
     val orderingD: Ordering[IntTuple] = Ordering.by(_.d)
   
     val fullOrdering: Ordering[IntTuple] =
       orderingA
         .thenOrderingBy(orderingB)
         .thenBy(orderingC)
         .thenBy(orderingD)
   }

   ord2

9.  def thenOrderingBy(ord2: Ordering[T]): Ordering[T]

   Returns a new Ordering which compares elements using the specified Ordering if this Ordering returned 0 when comparing them.

   This method is intended to be used to build more complex Orderings from other Orderings, as in the following example:

   case class PlayingCard(rank: Rank, suit: Suit)
   
   object PlayingCard {
     val rankOnlyOrdering: Ordering[PlayingCard] = Ordering.by(_.rank)
     val suitOnlyOrdering: Ordering[PlayingCard] = Ordering.by(_.suit)
