Augment the Error object with properties that explain details

I am catching an error and sending a response with Express + DoqmentDB like this:

```
foo.create({
foo: bar
}).then(function () {
res.json("Success");
}).catch(function (err) {
res.status(500).json(err);
});
```

The object is just:

```
[Error: Invalid value in: `foo`]
```

What I would like to see is something similar to [this section in the developers/node/design](https://www.joyent.com/developers/node/design/errors#4-augment-the--code-error--code--object-with-properties-that-explain-details) guide, where the error object is augmented with a name, message and the stack trace.
