Moved ancillary methods off specialized traits.

Moved compose/andThen off Function1, curried/tupled off Function2.
Pushed Tuple2 zipped into auxiliary class.  Created implicits to
plaster over the changes.  This drops several hundred classfiles and
takes (unoptimized) scala-library.jar from 7.8 Mb to 7.4 Mb.
