/*adding a second outlet for maximum value's idx, adding maximum_free, rewriting maximum_list
plus, de-fitter and loud-izing! basically rewrote the whole thing...
NOTE: in max, sending a list with one float totally borks up the test value, decided to set max 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 max of the list not counting the first elt, despite what the docs say (test value being the second largest). I'm following the docs in this case.
