Title: Update for_expr docs.

The old documentation for for loops/expressions has been quite wrong since the change to iterators. This updates the docs to make them relevant to how for loops work now, if not very in-depth. There may be a need for updates giving more depth on how they work, such as detailing what method calls they make, but I don't know enough about the implementation to include that.
