Consider adding location generators

[querkmachine]

An early feature that was planned but not implemented was the creation of location-related generators.

This included technical generators, such as coordinate systems, and postal address generators.

Generators highly considered for implementation:

• Latitude and longitude, using the decimal coordinate notation used by many online services and APIs (e.g. Google Maps)
• Street addresses
• Town and region names

Generators that are lower priority but may be useful:

• Latitude and longitude, using the degree-minute-second (DMS) coordinate notation
• US ZIP codes
• UK postcodes

Although generation of postal addresses may be difficult to do satisfyingly well, coordinate systems may be simpler.
