  Description     : Java implementation of arithmetic coding and PPM compression

 Arithmetic coding is a general technique for coding the outcome of a
 stochastic process based on an adaptive model. The expected bit rate
 is the cross-entropy rate of the model versus the actual process.
 PPM, prediction by partial matching, is an adaptive statistical model
 of a symbol sequence which models the likelihood of the next byte
 based on a (relatively short) suffix of the sequence of previous
 bytes.
