the exchange API for nodejs module


## Install

```bash
$ npm install --save viewpoint
```


## Usage

```javascript

var client = new EWSClient(username, password, ewsUrl, config);
client.syncFolders().then(function(res) {
  console.log('sync folders successfully!');
});
```

More examples can refer to `examples/` in the source repo.

## API

Many API function return the `Promise` object. For simplicity, I will use `Promise(ObjectType)` to represent the Promise object that return the `ObjectType` object. e.g. for function `foo` that return `Promise(Number)`, you can invoke it with
`foo().then(number) {}`.
