The node set consists for now of eleven nodes (5 unique, and 2 sets of convenience nodes).
Sort with index
This takes a real-list as an input, and gives out a sorted list from highest to lowest number. More importantly it also spits out an index list of where the highest number exists in the input list. It does this in a highly inefficient manner mind you (at least I think so∞), so connecting it straight to an audio-rate node will choke your composition. Please see example for how to do so under somewhat safe circumstances.
