I was looking for a way to grab the result of a mocked call. Currently, I'm just peeking into meck:history().

So I went to implement something like meck:capture(..., result), when I noticed that meck_history:result() exists. It was added in #163.

But it was demoted from the top-level meck API. I think this was a mistake -- it ought to be at the same level of abstraction as meck:capture.

Can we put it back? Or can we make meck:capture take ArgNum | result...?
