Re: [web-nfc] Attach to navigator (#602)

Let's have some JS examples for option 2 above. [Example 4]() has to use `ignoreRead`, with option 2 `ignoreRead` is not needed.

```javascript
navigator.nfc.scan();  // start NFC polling
navigator.nfc.ontagfound = event => {
  if (event.ndef) {
    event.ndef.write(data).then({
      console.log("Tag written");
    });
    ndef.read().then( message => {
    });
  }
}
```
