Description
I'm surprised we don't get the option of choosing between a spherical and linear formula for calculating distances. For search-engines that need to query large amount of objects based on relatively small distances this makes a fairly big performance difference and other libraries like Geokit have this implemented throughout.

Research direction
Start by locating the distance_between entry point and the existing distance-calculation tests. Review how the current formula is selected and how callers provide options. Done means users can choose between spherical and linear calculations, with coverage for both choices and the reported small-distance use case.
