Started reflecting QIO in the spec I/O chapter.
Started reflecting QIO in the spec I/O chapter.

For now, the text follows the existing QIO code (with minor exceptions).
Further modifications are eminent due to an upcoming spec/code review.

A variety of TODO comments indicate future spec work.

Sections "write, writeln, read, readln" through the rest of the chapter
have received minimal review and need more updating.

The contents heavily rely on/borrow from documentation and feedback
by Michael Ferguson.
