If Nodes only have the one output, we don't need to do so much differentiation between them. Previous iteration used outputs as like a distinct function within a Node (e.g. length output would return one result, buffer output would produce a different result - each run different code to produce their results). Now in this iteration, it's more accurate to say a Node is just one function (which seems more appropriate for a node system anyway).
