Geocoding

You could do it on the fly, but it would be faster to read the addresses
from a database table, geocode them, and write the latitudes and longitudes
to a table ahead of time so that when you are generating the map all you
have to do is a database lookup to get the coordinates instead of executing
the geocoding script for each address every time a map is generated.
