Yet another run at reduce

[Brian Goetz]

And then...

   into(collection)

becomes

   reduce(intoList())
   reduce(intoSet())
   reduce(intoCollection(ArrayList::new))

where intoList() could be as simple as:

     public static<T>
     Reducer<T,List<T>> intoList() {
         return intoCollection(ArrayList<T>::new);
     }

and intoCollection is as shown below.

Then into() goes away.

Then sequential() goes away.
