usage: ./export_layer.rb <-D storage_path> <-F format> <-E dir> <-Z zoom> <-W width> <-H height> <-l> <-h> layer <layers>
    -D  Use specified database location
    -F  Use specified export format (png, shp)
    -E  Use specified export directory path (default '.')
    -Z  Zoom in by specified factor (eg. 3.0)
    -W  Image width (default 600)
    -H  Image height (default 400)
    -l  List existing database layers first
    -h  Display this help and exit
  The layer(s) should be pre-existing layers (including dynamic layers) in the database.
  Supported formats are 'shp' for ESRI Shapefile and 'png' for images.

For example:
  ./export_layer.rb -D db -E exports -F png croatia.osm highway highway-residential natural-water

This will export four previously defined layers to png format files in the 'exports' directory.
