Details
kml files can be quite large (100k-600k per country) making
downloading them every time you want to make a map time
consuming. To reduce this time it's easiest to download
kml files and store them. To set the directory use a line
like this: options(kmlpath="/Users/emh/kmltemp") The
option must be called "kmlpath". These files will be
persistent until you delete them.
