function edges2d(varargin)
%EDGES2D Description of functions operating on planar edges.
%
% An edge is represented by the coordinate of its extremities:
% EDGE = [X1 Y1 X2 Y2];
%
% Centered edges are sometimes used (for example for representing main
% axes of an ellipse or an oriented box). Centered edges are represented
% by their center, their length, and their orientation (counted in
% degrees and counter-clockwise).
% CEDGE = [XC YC LEN THETA];
%
% A set of edges is represented by a N-by-4 array, each row representing
% an edge.
