Relationship to itertools

The itertools package (with an s) is a package in the standard library. It differs from itertoolz (with a z) in the following ways.

• itertools has an s. itertoolz has a z.

• itertools is strictly a library of [streaming algorithms](http://en.wikipedia.org/wiki/Streaming_algorithm) while itertoolz accepts functions that require finite iterators.

• itertools changes very slowly and is managed by the official Python community (you submit a PEP). itertoolz is more loose (you submit a pull request)

• itertools is minimal. itertoolz accepts recipes.
