Update doc by first remove the old doc and then running m2html('mfiles','fun', 'htmldir','doc', 'recursive','on') for each of the 4 folders in labtools; The replacement process was needed to remove docs for files that don't exist anymore.
the last time doc was generated was 8 years ago. The file structures and a lot of files have changed. The files that had a structural change will be shown as a delete and then addition instead of tracked changes
