从google开源项目LitJson上取出的LitJson源码。为纯cs文件。将其解压，放到你的项目中即可使用LitJson库了。例如：unity不支持json的处理，把解压的文件放到Unity3d的assets中的plugins目录下，即可在项目中using LitJson了。

-The source of LitJson removed from google open source project LitJson. Pure cs file. Extract, you can use LitJson library into your project. For example: unity does not support json processing, unzip the file into the plugins directory Unity3d' s assets, you can project using LitJson.
