OK, going back to multiple files (see #23)
cleared up remaining compiler warnings (fixes #7)

OK I'm sort of cheating here, but at this point I've got like 3
issues all dealing with docs; so in my head I have a system for
when each gets closed (#26 is last for some reason) and this one
was really just waiting for the "come back to the compiler
warnings part and fix that" step.
include StreamLikeSequence in docs (see #8)
