Investigate EXINT encoding

Hi, this reminded me of something a buddy of mine wrote. I'm not sure whether this will be useful, but I thought I'd drop the link just in case.

Don't believe this is too relevant here since we are typically more interested in faster processing and the overhead in encoding/decoding from a universal code would cause a slow-down in the hot loop. The possible stored size improvements are only interesting on huge integers and I expect that even then it would be negigible or evne worse than storing them directly, since typically the words of a big integer can be expected to be relatively random (if calculations aren't centered around a power-of-2 base).

Anyway, thanks for the link!
