James Reggio 8d757e5ad7 Export Animated.Node for ease of type checking ...

Summary:
At present, there's no uniform way of determining whether you've received an Animated value node which can be attached to an animated prop.

You can attempt to use `instanceof Animated.Value`, but this fails for interpolated values. You can use `instanceof Animated.Interpolation`, but this fails for the values that are returned from the math functions (e.g., `Animated.Add`).

This commit exposes the base type from which all of these value nodes derive. As such, it is now possible to do the following:

```js
import React, { Component, PropTypes } from 'react';
import { Animated } from 'react-native';

class Widget extends Component {
  static propTypes = {
    progress: PropTypes.instanceOf(Animated.Node).isRequired,
  }
  // ...
}
```

Unnecessary for cosmetic change.
