Querying JSON with SelectToken

This sample loads JSON and then queries values from it using Argon.JToken.SelectToken(System.String).

var o = JObject.Parse(
    """
    {
      'Stores': [
        'Lambton Quay',
        'Willis Street'

      'Manufacturers': [
        {

            {
              'Name': 'Anvil',
              'Price': 50
            }
          ]
        },
