/*
* mulitplex : zpack a specified input to the output
*
* THINK: should the selector-inlet be the first or the last ???
* pros/cons:
* the 1st inlet being the selector is not consistant with pd (hot/cold)
* but as it since the hot inlet is selectable, the whole object is not really consitant
* numbering would have to start with 1 (for the 1st not-leftmost inlet)
* if the selector is rightmost this would mean: cold is right(most), hot is (somewhere) left
* numbering would be ok
*
* conclusio: make the selector rightmost
