Dotliquid使用Json模板变量

Dotliquid是不错的Template Engine，为了更方便使用，扩展了一下，使它支持json数据的替换，引用了Newtonsoft.Json.Linq

        /// 从JObject创建模板变量
        /// </summary>

        /// <returns></returns>
        protected Hash FromJson(JObject jsonObject)
        {
            if (jsonObject == null) return null;
            var hash = new Hash();
            foreach (JProperty item in jsonObject.Children())
            {
                if (item.HasValues && item.Type == JTokenType.Property)
                {
                    switch (item.Value.Type)
                    {

                                hash.Add(item.Name, FromJson(jObj));
