Title: More intuitive map_reduce laziness

Fix for #2264.

I added `map_reduce#inspect` and `map_reduce#execute`

Let me know what you think. The one thing that bummed me out a little is that I don't do a good job indenting the `#inspect` output, since it has criteria's inspect embedded in it (give it a try to see what I mean).
