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