[Tutor] combining tuples in a list

[Lloyd Hugh Allen]

I use 2.2. Needed to have 2.2 to use Danny's "Permutations using
Generators" to answer a friend's problem.

Now that I look more closely at inheritance, I could have overwritten
the __add__ method, but then within it called tuple.__add__(self,
other[1:]) to make the code more transparent. Don't want to repost the
whole big thing though.

A complete solution, then, would also have to check and make sure that
you don't have (abc)(cda), which would yield an animal with its head at
its tail.
