Added tool for analyzing forwarder classes.

If you build and then run

    tools/proxy-report <outdir>

you will be given files revealing interesting things like:

  /** With respect to trait SetLike, trait SetProxyLike does NOT wrap:
  */

  trait Unwrapped {
    def +(elem1: A,elem2: A,elems: A*): This
    def ++(elems: scala.collection.GenTraversableOnce[A]): This
    def subsets(len: Int): Iterator[This]
    def subsets: Iterator[This]
    protected override def newBuilder: scala.collection.mutable.Builder[A,This]
    protected override def parCombiner: scala.collection.parallel.Combiner[A,scala.collection.parallel.ParSet[A]]
  }

Lots more possible here, for now I just want to get a backstop

against our worst transgressions (not just in the library -- look
at SimpleTypeProxy, if you dare!) I will inquire about the results
separately, so no review.
