    filename and path strings. Multiple choices are possible, as well as
    directory names. Both returned values are then char or cellstr.

    Use strcat(pathname, filesep, filename) to obtain full file name.

    options may be: 'Location', [x y]
                or  [x y]
            and     'MultiSelect', 'on'|'off'
