Description: Iterative least cost path and minimum spanning tree
        methods for projecting forest road networks. The methods
        connect a set of target points to an existing road network
        using 'igraph' <https://igraph.org> to identify least cost
        routes. The cost of constructing a road segment between
        adjacent pixels is determined by a user supplied weight raster
        and a weight function; options include the average of adjacent
        weight raster values, and a function of the elevation
        differences between adjacent cells that penalizes steep grades.
        These road network projection methods are intended for
        integration into R workflows and modelling frameworks used for
        forecasting forest change, and can be applied over multiple
        time-steps without rebuilding a graph at each time-step.
