// Model obtained from a 2-sided zero-centered distribution derived
// from a Pareto distribution. The cdf of the distribution is:
// cdf(x) = 0.5 + 0.5 * sgn(x) * [1 - {alpha/(alpha + |x|)} ^ beta]
//
// For a given beta and a given probability of the 1-node, the alpha
// is first solved, and then the {alpha, beta} pair is used to generate
// the probabilities for the rest of the nodes.
//
// The full source code of the generating program is available in:
// tools/gen_constrained_tokenset.py
//
// Values for tokens ONE_TOKEN through CATEGORY6_TOKEN included here.
// ZERO_TOKEN and EOB_TOKEN are coded as flags outside this coder.
