It seems unwise to let NodeInputs take more than one value, but at times it makes sense to create a list or array of inputs. This class will create sub-parameters as an easy way to provide variable inputs while also enforcing one connection per input parameter. This is also the primary motivation for the previous commit (disambiguating when a NodeParam's parent is a Node vs some other type).
