I'd like to set default inputs for a custom NodeModel node such as in:

https://github.com/DynamoDS/Dynamo/blob/master/src/Libraries/CoreNodeModels/Range.cs#L33

Currently this can be done in the main constructor via InPorts.Add(new PortModel(PortType.Input, this, new PortData("","", defaultValue))); but not in the JsonConstructor because PortModel.DefaultValue has an internal setter.

I believe this is a bug and the setter should be made public so that default values can be set correctly also when opening saved definitions.
