In functions4common.py, it now detects ways and areas as well. Whether it's a way or an area is defined in all_elements. This matters because the shapefile has an explicit distinction between ways and areas.

Remaining major things to get done.
- Assign the already written functions to handle the various identified nodes/ways/areas.
- Download the Coastlines (this will probably take a while).
