function filenames = read_dir(dirname, ext, prepend)
% READ_DIR Like the built-in dir command, but returns filenames as a cell array
% filenames = read_dir(dirname, ext)
%
% e.g., filenames = read_dir('images', '*.jpg')
% filenames{1} = 'foo.jpg', filenames{2} = 'foo2.jpg', etc
%
% read_dir(dirname, ext, 1) means pre-prend the directory name
%
% e.g., filenames = read_dir('images', '*.jpg', 1)
% filenames{1} = 'images/foo.jpg', filenames{2} = 'images/foo2.jpg', etc
