% GRID2EDGES   Estimates grid edges for a set of grid points.
%
%    Between defined grid points, the edge is defined as the middle point. 
%    End edges are set based on the distance between the two closest points.
%
% FORMAT   e = grid2edges(g)
%        
% OUT   e   Edges of grid ranges.
% IN    g   Grid points.
