%         distance : Computes the list of pairwise distances for a given set of locations
%   find_neighbors : finds observations containing m nearest neighbors, slow but low memory version
%          find_nn : finds observations containing m nearest neighbors, fast but high memory version
%         find_nn2 : finds observations containing nn nearest neighbors, high-order search
%        make_html : makes HTML verion of contents.m files for the Econometrics Toolbox
