create_buffer

Called from within create_grid function, this function takes the bounding
box of a group of polygons, or a specific table of minimum and maximum
longitudes and latitudes to create points for each polygon to be allocated
to that will tessellate into hexagons.

Create a hexagon tile map display from spatial polygons. Each
polygon is represented by a hexagon tile, placed as close to it's original
centroid as possible, with a focus on maintaining spatial relationship to
a focal point. Developed to aid visualisation and analysis of spatial
distributions across Australia, which can be challenging due to the
concentration of the population on the coast and wide open interior.
