[collections] MultiKey

[Stephen Colebourne <sc...@btopenworld.com>]

I have written and checked in a MultiKey class. This is based on a class
from Tapestry and also from a similar class I have used in my day job.

It enables multi-level map lookups to be flattened by creating a combination
hashkey, for example to lookup a filename in a specific locale by key you
might use:
  String filename = (String) map.get(
    new MultiKey(key, locale)
  );

Cool.  MultiKey was a good choice, but so modest I didn't dare suggest it.

Check out BinaryDumpOutputStream, it's handy!
