-All bits are either '1' or '0' characters.
-All bitstrings are a sequence of '1' and '0' characters. The right-most
-character in the bitstring is the LSB. Example: '01110001' (1 is LSB).
+All bitstrings are a list consisting of two items. The first is a sequence
+of '1' and '0' characters (the right-most character is the LSB. Example:
+'01110001', where 1 is the LSB). The second item is a list of ss/es values
