Unlisted dependencies

[j-dr]

In the process of installing kungpao, I noticed that Erin Sheldon's smatch and cosmology packages also appear to be dependencies. It's probably worth listing these in the readme along with the other dependencies.

I downloaded smatch and cosmology but keep getting the error "cannot import name '_smatch' from 'smatch'" where its halting when smatch.py tries to call "from . import smatch"
