* React component that wraps the platform `DrawerLayout` (Android only). The
* Drawer (typically used for navigation) is rendered with `renderNavigationView`
* and direct children are the main view (where your content goes). The navigation
* view is initially not visible on the screen, but can be pulled in from the
* side of the window specified by the `drawerPosition` prop and its width can
* be set by the `drawerWidth` prop.
*
* Example:
*
* ```
* render: function() {
* var navigationView = (
* <View style={{flex: 1, backgroundColor: '#fff'}}>
* <Text style={{margin: 10, fontSize: 15, textAlign: 'left'}}>I'm in the Drawer!</Text>

* drawerWidth={300}

* <View style={{flex: 1, alignItems: 'center'}}>
* <Text style={{margin: 10, fontSize: 15, textAlign: 'right'}}>Hello</Text>
* <Text style={{margin: 10, fontSize: 15, textAlign: 'right'}}>World!</Text>
