/*adding a second outlet for minimum value's idx, adding minimum_free, rewriting minimum_list
plus, de-fitter and loud-izing! basically, rewrote the whole thing...
NOTE: in min, sending a list with one float totally borks up the test value, decided to set min value to this instead
also, the test value set from a list retains its index when floats are sent after
(if test < float input, old idx from list gets sent out right inlet)
here, just set to 1
-alexandre notes that the test value from a list is the min of the list not counting the first elt, despite what the docs say (test value being the second smallest). I'm following the docs in this case.
