duplicated_tol          Identify duplicated values in a sorted numeric
                        vector, where comparison is up to a specified
                        numeric tolerance. If there is a run of values
                        where each consecutive pair is closer together
                        than the tolerance, all are labeled as
                        duplicates even if not all values in the run
                        are within the tolerance.
get_dup_run_inds        Get indices of starts and ends of runs of
                        duplicate values
make_d_fn               Creates a function that evaluates the
                        probability density function of an
                        approximation to a distribution obtained by
                        interpolating and extrapolating from a set of
                        quantiles of the distribution.
make_p_fn               Creates a function that evaluates the
                        cumulative distribution function of an
                        approximation to a distribution obtained by
                        interpolating and extrapolating from a set of
                        quantiles of the distribution.
make_q_fn               Creates a function that evaluates the quantile
                        function of an approximation to a distribution
                        obtained by interpolating and extrapolating
                        from a set of quantiles of the distribution.
make_r_fn               Creates a function that generates random
                        deviates from an approximation to a
                        distribution obtained by interpolating and
                        extrapolating from a set of quantiles of the
                        distribution.
mono_Hermite_spline     Create a polySpline object representing a
                        monotonic Hermite spline interpolating a given
                        set of points.
spline_cdf              Approximate density function, CDF, or quantile
                        function on the interior of provided quantiles
                        by representing the distribution as a sum of a
                        discrete part at any duplicated 'qs' and a
                        continuous part for which the CDF is estimated
                        using a monotonic Hermite spline. See details
                        for more.
split_disc_cont_ps_qs   Split ps and qs into those corresponding to
                        discrete and continuous parts of a
                        distribution.
step_interp_factory     A factory that returns a function that performs
                        linear interpolation, allowing for "steps" or
                        discontinuities.
unique_tol              Get unique values in a sorted numeric vector,
                        where comparison is up to a specified numeric
                        tolerance. If there is a run of values where
                        each consecutive pair is closer together than
                        the tolerance, all are labeled as corresponding
                        to a single unique value even if not all values
                        in the run are within the tolerance.
