Mixing up "input" and "output" in prose description of wiring composition

[kevinclancy]

In chapter 1, the text "An outer output port is weired to a middle output port, and this middle output port is wired to an inner input port" should be changed to "An outer output port is weired to a middle output port, and this middle output port is wired to an inner output port"

In the next bullet point, "A inner output port is either wired to an inner input port or a middle input port. If it is wired to an inner input port, we leave it that way" should be changed to "An inner output port is either wired to an inner output port or a middle input port. If it is wired to an inner output port, we leave it that way"
