Description: Uses the generalized ratio-of-uniforms (RU) method to
        simulate from univariate and (low-dimensional) multivariate
        continuous distributions. The user specifies the log-density,
        up to an additive constant. The RU algorithm is applied after
        relocation of mode of the density to zero, and the user can
        choose a tuning parameter r. For details see Wakefield, Gelfand
        and Smith (1991) <DOI:10.1007/BF01889987>, Efficient generation
        of random variates via the ratio-of-uniforms method, Statistics
        and Computing (1991) 1, 129-133.  A Box-Cox variable
        transformation can be used to make the input density suitable
        for the RU method and to improve efficiency.  In the
        multivariate case rotation of axes can also be used to improve
        efficiency. From version 1.2.0 the 'Rcpp' package
        <https://cran.r-project.org/package=Rcpp> can be used to
        improve efficiency.
