nodejs addon C++自动翻译成js

运行gen.py将解析C++代码并生成一个C++导出文件和一个js文件，c++导出文件用于生成dll导出函数供js调用，js和c++接口一一对应。程序员只需编写C++代码和js调用，省去addon繁琐的接口适配。支持异步调用和delegate。

js调用c++测试代码：

var delegate = {
        OnTestObject: function(ts, a) {
          log("OnTestObject : " + JSON.stringify(ts) + " " + a);
        },
        OnTestInt: function(value) {
          log("OnTestInt : " + value);
        },
        OnTestList: function(value) {
          log("OnTestList : " + JSON.stringify(value));
        },
        OnTestMap: function(value) {
          log("OnTestMap : " + JSON.stringify(value));
        }
      }
      var tc = new TestClass();
      tc.SetDelegate(delegate);
      var obj = {
        n: 125,
        s: "hello 世界",
        d: 0.5,
        b: false,
        e: 3
      }
      // 直接调用
      log(JSON.stringify(tc.TestObject(obj, 22)));
      // 异步调用，启动线程调用C++ TestObject接口，调用完成通过callback返回结果
      // 最后一个参数传递function表示异步调用
      tc.TestObject(obj, 22, function(retval) {
        log(JSON.stringify(retval));
      });
      log(tc.TestString("hello 世界!"));
      log(tc.TestInt(22));
      log(tc.TestBool(true));
      log(tc.TestDouble(5.1));
      log(tc.TestEnum(3));
      log(tc.TestVoid());
      log(JSON.stringify(tc.TestList(["hello", "world"])));
      log(JSON.stringify(tc.TestMap({
        "hello": {"he":"llo"},
        "world": {"wo":"rld"}
      })));
      
      var delegate1 = {
        OnTestObject: function(ts, a) {
          log("OnTestObject-- : " + JSON.stringify(ts) + " " + a);
        },
        OnTestInt: function(value) {
          log("OnTestInt-- : " + value);
        },
        OnTestList: function(value) {
          log("OnTestList-- : " + JSON.stringify(value));
        },
        OnTestMap: function(value) {
          log("OnTestMap-- : " + JSON.stringify(value));
        }
      }
      var delegate2 = {
        OnTestInt2: function(value) {
          log("OnTestInt2 : " + value);
        }
      }
      var tc2 = new TestClass();
      tc2.SetDelegate(delegate1);
      tc2.SetDelegate2(delegate2);
      log(tc2.TestInt(5));
