### NAN_CONSTRUCTOR(methodname)
Use `NAN_CONSTRUCTOR` to define constructors used by your V8 accessible methods:

```c++
struct Foo {
NAN_CONSTRUCTOR(Foo);
...
};

NAN_CONSTRUCTOR(Foo::Foo) {
...
}
```

The reason for this macro is that constructors have no explicit return type and cannot thus be declared the way methods are.
