/**
 * @brief Class for asynonymous substitution models on codons with
 * parameterized equilibrium frequencies and nucleotidic basic models.
 *
 * @author Laurent Guéguen
 *
 * This class should be used with models which equilibrium
 * distribution is fixed, ans does not depend on the parameters.
 * Otherwise there may be problems of identifiability of the
 * parameters.
 *
 * See description in AbstractCodonDistanceSubstitutionModel and
 * AbstractCodonPhaseFrequenciesSubstitutionModel class.
 *
 * Only substitutions with one letter changed are accepted. </p>
 *
 * The additional parameter to CodonPhaseFrequenciesSubstitutionModel
 * is the ratio of nonsynonymous over synonymous substitutions.
 *
 * If a distance @f$d@f$ between amino-acids is defined, the ratio between
 * non-synonymous and synonymous substitutions rates is, if the codied
 * amino-acids are @f$x@f$ and @f$y@f$, @f$\beta*\exp(-\alpha.d(x,y))@f$ with
 * non-negative parameter @f$\alpha@f$ and positive parameter @f$\beta@f$.
 *
 * If such a distance is not defined, the ratio between non-synonymous
 * and synonymous substitutions rates is @f$\beta@f$ with positive
 * parameter @f$\beta@f$.
