% Distances
%   spheredist    - Computes great circle distances on a sphere.
%   spheresort    - Sorted great circle distances to nearby points on a sphere.
%   inregion      - Tests whether lat/lon points lie within a specified box.
%   lonshift      - Shifts longitude origin for plotting purposes.
