Description: A set of fast and convenient functions to help conducting
        accessibility analyses. Given a pre-computed travel cost matrix
        and a land use dataset (containing for example the location of
        jobs, healthcare and population), the package allows one to
        calculate accessibility levels, and accessibility poverty and
        inequality. The package covers the majority of the most
        commonly used accessibility measures (such as cumulative
        opportunities, gravity-based and floating catchment areas
        methods), some cutting edge measures proposed in the literature
        (e.g. balancing cost and constrained accessibility) as well as
        the most frequently used inequality and poverty metrics (such
        as the Palma ratio, the concentration and Theil indices and the
        FGT family of measures).
