calculate_cell_size

Given an input multipolgyon spatial data frame this function calculates the
required cell size of a regular or hexagonal grid.

Turn irregular polygons (such as geographical regions) into regular or hexagonal grids.
This package enables the generation of regular (square) and hexagonal grids through the package
'sp' and then assigns the content of the existing polygons to the new grid using
the Hungarian algorithm, Kuhn (1955) (<doi:10.1007/978-3-540-68279-0_2>).
This prevents the need for manual generation of hexagonal grids or regular grids
that are supposed to reflect existing geography.
