- * 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
+ * (c) 2007-2011 forum::für::umläute
*
- * conclusio: make the selector rightmost
