Lilo : Fast and pixel-accurate stitching for 2D tiles

% Written by Maxime Deforet, April 5. 2012.
% INPUT :
% - mozaic : array of "overlapping graph"
% exemple : [[1,2];[2,3];[3,4];[4,5];[3,6];[6,7];[7,8];[8,9];[9,10]];
% for
% 2 1
% 3 4 5
% 6 7 8
% 10 9
% - files : array of N cells, each of these cells is the full path of the tile i.
% example :
% folder='/home/your_images';
% files=dir(folder);
% files=sort_nat({files.name});
% for i=1:10
% Files{i}=fullfile(folder,files{i});
% end
%
% OUTPUT :
% - A : stitched image from tiles
% - Xmozaic : xy positions of tiles
