osmtile_bbox

inspired by <code>osmtile</code> from the package <code>OpenStreetmap</code>returns the Mercator projection bounding box

Serves two purposes: (i) Provide a
comfortable R interface to query the Google server for static
maps, and (ii) Use the map as a background image to overlay
plots within R. This requires proper coordinate scaling.
