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).
