More Itertools

I love itertools; it's one of the most beautiful, composable standard libs. "Aha! I have an iteration problem here; I'm sure there is an itertools routine that fits it perfectly" oft passes my lips. My confidence is typically well-placed, but sometimes, neither itertools nor the recipes included in its docs do quite what I need.

Here I've collected several routines I've reached for but not found. Since these are deceptively tricky to get right, I thought I'd wrap them up into a library. Enjoy! Any additions are welcome; just file a pull request.

Run the tests

This uses nose for tests. First, install nose:

pip install nose

Then, run the tests like this:

nosetests

It should also be possible to say python setup.py test. However, some part of the test runner throws an error after the tests pass.
