-'''
-A class which presents the reverse of a sequence without duplicating it.
-From: "Steven D. Majewski" <sdm7g@elvis.med.virginia.edu>
-
-It works on mutable or inmutable sequences.
-
->>> chars = list(Rev('Hello World!'))
->>> print ''.join(chars)
-!dlroW olleH
-
-The .forw is so you can use anonymous sequences in __init__, and still
-keep a reference the forward sequence. )
-If you give it a non-anonymous mutable sequence, the reverse sequence
-will track the updated values. ( but not reassignment! - another
-good reason to use anonymous values in creating the sequence to avoid
-confusion. Maybe it should be change to copy input sequence to break
-the connection completely ? )
