After some discussion yesterday with @ctubbsii we came up with a
compromise, that I believe will benefit everyone. I can document the interface
to follow the design that states "All Iterators must close their source" but
maintain the a lot of the current interaction with Iterators (mainly RFile,
SourceSwitchingIterator and Scanner). They ARE grandfathered in right? ;)
