When saving large arrays with repeated elements, data compression can save a huge amount of space.

This BSD licensed toolbox by Kota Yamaguchi uses matlab java interface to support gzip and zlib based compression. Use it for now.

For octave, need to find alternatively solution.

Ultimately, need a mex-based gzipencode/zlibencode package for portability.
