Mention stopifnot() and general assertion strategies? #17

Nice debugging chapter. Relying a stopifnot("error message here" = condition_to_meet(), "another error" = another_condition()) is a good pattern worth mentioning.

Thanks! I'm planning to have "Error Debugging" separate from "Error Design and Handling". So, I'll make sure stopifnot() is covered in that section. 👍

If we're picky we could say it's neither but belongs in a section such as this. Anyway, I trust you'll get it covered.
