cheap-ruler

A collection of very fast approximations to common geodesic measurements. Useful for performance-sensitive code that measures things on a city scale.

This is a port of the cheap-ruler JS library and cheap-ruler-cpp C++ library into safe Rust.

Note: WGS84 ellipsoid is used instead of the Clarke 1866 parameters used by the FCC formulas. See cheap-ruler-cpp#13 for more information.
