storing to a file

[John Meacham]

right now DrIFT derives NHC type binary instances, I actually modified a
version to work with GHC but I just use it internally since among other
things it uses zlib (via libz and the FFI) to compress its output too
and is optimized for dumping and reading an entire structure from a
single file so is less general purpose than the current Binary library.
I will definatly accept any modifications/new derivation rules anyone
has. I regularly use it to dump and read data files many megabytes in
size after binary compression then zlib compression. takes a fare bit of
RAM for the raw haskell representations though.
