    Template trait to define Foldable in terms of foldMap.

    Template trait to define Foldable in terms of foldMap.

    Example:

    new Foldable[Option] with Foldable.FromFoldMap[Option] {
      def foldMap[A, B](fa: Option[A])(f: A => B)(implicit F: Monoid[B]) = fa match {
        case Some(a) => f(a)
        case None    => F.zero
      }
