让JS自动匹配出protoJs的方法

 args = [].slice.call(arguments, 1 obj = ( i = 0; i < args.length; i++ p = key = i + 1 protobuf.Field(p[0], key, p[1] || "string" obj = ( i = 0; i < list.length; i++ ( protobuf == "undefined") ;= protobuf.Root().define("IMEntity""Token", ["UserID"], ["Token"], ["Device"], ["Version", "int32"], ["Appkey""Feedback", ["ResultCode", "int32"], ["ResultData"], ["Seq", "int32"], ["MsgID""ReceiptType", ["Receive", "Read"
 };

var Root = protobuf.Root,
 Type = protobuf.Type,
 Field = protobuf.Field;var AwesomeMessage = new Type("AwesomeMessage").add(new Field("awesomeField", 1, "string"));var root = new Root().define("awesomepackage").add(AwesomeMessage);
