-This module has only one method substrings. It is called as
-substrings STRING [,LENGTH]. Without a length specification, it
-returns all substrings with a length of 1 or greater including the
-string itselfs. The substrings returned are sorted for the length
-(starting with length 1) and for their index. E.g. substrings "abc"
-returns ("a","b","c","ab","bc","abc"). This order is guaranteed to
-stay even in future versions. That also includes that the returned
-list of substrings needn't be unique. E.g. substrings "aaa" returns
