Octave-Forge, Source coding: Tunstall code, Huffman code

Hi David,
I have some source coding algorithms, I would like to see included into 
Octave-forge communications package, as I see it already has
implementations for arithmetic encoding & decoding,  some quantization
algorithms etc.

Im presently adding it with the Information theory package, but with
the other codecs in comm' package we might have to start a new
branch of source coding algorithms only or merge with existing.
Merging seems less work, and useful.
