Utilites for handling lists and filenames

rm_ext.py

    """Removes extension from filename"""
    if not ext:
        ext = re.match(".*\.(.*)$", fname).group(1)

uniq_list.py

def uniq_list(array):
    """ Returns unique elements in list in original order

    set() does not preserve order. In python 3.5, OrderedDict is implemented in C,
    and thus acceptable alternative. For python 3.6+, it can be replaced with regular
    dict as it became ordered.
