please confirm dependences

Could you clarify the statement:

It is developed in Cython, but requires no dependecies other than CPython and a C compiler.

However, it seems uses toolz:
https://github.com/pytoolz/cytoolz/blob/master/cytoolz/_signatures.py#L1-L2

from toolz._signatures import *

I see, the README does need updated to mention toolz. Yes, toolz is required and is in the install_requires metadata:

cytoolz/setup.py

Line 133 in 85b03a5

install_requires=['toolz >= 0.8.0'],

Good catch, thanks!
