SMAC - Short Message Arithmetic Compressor
------------------------------------------
(C) Serval Project Inc., and Flinders University 2012-2015.

SMAC compresses SMS and Twitter like messages to around half of their original size, often less.
It uses a compressed pre-computed multi-order dictionary to feed probabilities to an arithmetic coder.
It offers full unicode support, and accepts UTF-8 strings.  
Using redundancy in the UTF-8 format, SMAC offers the feature that it never increases
the length of a string during compression, and uncompressed strings can be passed to 
the decompressor without causing problems.

Short Messages," Int'l J. of Communications, Network and System Sciences, Vol. 6 No. 12, 2013, pp. 497-504.
