For WorldEngine 0.19.0

This application reads data from one or more WorldEngine ProtoBuf files and generates images from the data.

The application will take as an argument either a world file or a directory. If no argument is included, it will default to the current active directory. If a directory, it will look for files named *.world in the directory, and operate on each one. For each world file processed, the application will generate a corresponding height map, rainfall map, river map, and temperature map.

This version has been tested against WorldEngine 0.19.0, though should be compatible with future versions, if the ProtoBuf format used in those versions remains backwards compatible.
