Basically, change it so each input is a NumericVector, then loop spherical_distance for 1:length(lat1) ...etc.

This would also mean that we would remove maxcovr::spherical_distance, replacing it with the c++ function, which would be at least twice as fast.

This will not be relevant anymore once geodist is used, I don't think
