Adds feature comparison table to README (#7)

* Adds feature comparison table to README

So that people can get a quick sense of how Hamilton stacks
up against common things its compared to.

* Swaps pandas for Dask

Swaps pandas for dask because I think that comparison is made more often.

Also adds a row about code base organization.

* Fixes whitespace
