Investigate Integrating Toolz

[EntilZha]

Via Twitter got suggested to checkout toolz. I think its worth looking into as powering part of the backend. It may help clean up code, make certain things easier to extend, and improve performance.

I've posted to their mailing list expressing interest in collaboration.

Can add these projects to look at as well:

fn.py

Funcy

Thinking perhaps theme of 0.4.0 will be bringing in some utility things from other libraries and/or iterop with other formats, so marking this for 0.4.0

Looking at these, the one with the most potential to benefit from is the _ operator from fn.py. Most of the other things are either already in functional, or could be added. It also is hard to use them as underlying engines since there is already a custom pipelining engine.

Therefor, fn.py has been added as a dependency and is importable via from functional import _. The intent is that the only import required is from functional import seq, _. This was done in a009a67 and fixes for build issues in subsequent commits.
