 Description: Produces customisable images of OpenStreetMap data.  Extracts OpenStreetMap data for specified key-value pairs (e.g.  key="building") using the overpass API. Different OSM objects can be plotted in different colours using the function add_osm_objects().  The function group_osm_objects() enables customised highlighting of selected regions using different graphical schemes designed to contrast with surrounding backgrounds.
