Updated example to use ES6 features

Used imports instead of require.
Simplified imports and removed unused component View.
Background is now a const instead of var. <- ES6 prefers this
Removed dangling comma after background ```source={{uri: background, }}```

Generally example is more succinct and easier to understand for users only exposed to the new tools of ES6.
