The Stream Filter archetecture is finished, it's actually much cooler than I

had anticipated, and much cleaner.  I'll have to add some documentation to it,
because it's not really obvious how any of it fits together from the outset,
although I have to say that the bzip2 test program is the easiest general bzip2
compression program I've ever made...it just goes :)

Decompression in Bu::BZip2 isn't finished yet, but that's ok, it's coming soon.
