WeChat JSSDK supports namespace version (3.2)

Provides various official and user-released code examples and code reference. You are welcome to exchange and learn about the new version of jssdk provided yesterday. Here we modified it and supported the 3.2 version of the command space, debugging mode added at the same time!
/**
* Official documentation: http://mp.weixin.qq.com/wiki/7/aaa137b55fb2e0456bf8dd9148dd613f.html
* Example: http://demo.open.weixin.qq.com/jssdk/sample.zip
*
* The JSSDK class mainly modifies the mechanism for saving session information. In this example, files are used. The ThinkPHP cache mechanism is used here. For details, refer to the official example documentation.
* The debugging mode is added. The call example is as follows:
* $ Jssdk = new JSSDK (C ('wx _ APPID '), C ('wx _ SECRET '));
* $ Jssdk-> debug = true; // enable the local debugging mode. Put the two official json files in the same directory as the index. php file!
* $ SignPackage = $ jssdk-> GetSignPackage ();
* @ Namespace version
* @ Author Gump (QQ: 33808 624)
* @ Date
