% Author: Thokare Nitin D.
% 
% This function reads all file names contained in Datafolder and it's subfolders
% with extension given in extList variable in this code...
% Note: Keep each extension in extension list with length 3
% i.e. last 3 characters of the filename with extension
% if extension is 2 character length (e.g. MA for mathematica ascii file), use '.'
% (i.e. '.MA' for given example)
% Example:
% extList={'jpg','peg','bmp','tif','iff','png','gif','ppm','pgm','pbm','pmn','xcf'};
% Gives the list of all image files in DataFolder and it's subfolder
%
