They are written in C, so avoid a lot of CPython interpreter

I thought I would point out that many of the itertools functions
change between 2.x and 3.x versions. Since 2.7 is supposed to be the
last 2.x language, I suppose I will wait until 3.2 becomes the norm
before I incorporate some of these changes. In the mean time, I will
starting working on algorithms that work against Sequences.

I think a really important lesson is that Python really doesn't need
an algorithms library, like many others do. A lot of the common
algorithms are supported by the syntax itself. All my library did was
allow for easier function composition.
