Constructor names for These are now This/That/These rather than This/That/Both. Also added feed functions for process1 and wye.
attachL and attachR combinators, and a few other combinators needed for connectL/R
Basic unit test for feedL
Added connectL/connectR syntax
drainL/drainR combinators, renamed wye.observe to wye.drainR for consistency
