function edge = lineToEdge(line)
%LINETOEDGE Convert a straight line to a finite edge.
%
% EDGE = lineToEdge(LINE)
% Returns the edge with same origin as the line LINE, and with second
% extremity corresponding to the addition of line origin and direction.
% LINE is represented as [X0 Y0 DX DY]
% EDGE is represented as [X1 Y1 X2 Y2]
%
% Example
% line = [3 4 1 2];
% edge = lineToEdge(line)
% edge =
% 3 4 4 6
