func chilkatTest() {
    // Imagine we have two separate JSON objects.
    let jsonA = CkoJsonObject()!
    jsonA.update("animal", value: "zebra")
    jsonA.update("colors[0]", value: "white")
    jsonA.update("colors[1]", value: "black")

    jsonA.emitCompact = false
    print("\(jsonA.emit()!)")

    // jsonA contains:

    // {
    //   "animal": "zebra",
    //   "colors": [
    //     "white",
    //     "black"
    //   ]
    // }

    let jsonB = CkoJsonObject()!
    jsonB.update("type", value: "mammal")
    jsonB.updateBool("carnivore", value: false)

    jsonB.emitCompact = false
    print("\(jsonB.emit()!)")

    // jsonB contains:

    // {
    //   "type": "mammal",
    //   "carnivore": false
    // }

    // Let's say we want to insert jsonB into jsonA to get this:

    // {
    //   "animal": "zebra",
    //   "info" " {
    //       "type": "mammal",
    //       "carnivore": false
    // 	},
    //   "colors": [
    //     "white",
    //     "black"
    //   ]
    // }

    // First add an empty object at the desired location:
    jsonA.add(at: 1, name: "info")

    // Get the JSON object at that location, and load the JSON..
    var jsonInfo: CkoJsonObject? = jsonA.object(of: "info")
    jsonInfo!.load(jsonB.emit())
    jsonInfo = nil

    print("\(jsonA.emit()!)")

    // The end result is this:

    // {
    //   "animal": "zebra",
    //   "info": {
    //     "type": "mammal",
    //     "carnivore": false
    //   },
    //   "colors": [
    //     "white",
    //     "black"
    //   ]
    // }
