Add If and Box nodes

[liamgriffiths]

We've introduced two additional utilities nodes: Box and If

Box can be used to "shape" outputs and it will output the any data that has been provided as an input.

  new Box({
    value: {
      a: [1, 2, 3]
    }
  }) // outputs { a: [1, 2, 3] }

If can be used to output data conditionally.

  new If({
    condition: true,
    value_if_true: "yes",
    value_if_false: "no",
  }) // outputs { result: "yes" }
