Use WebView from react-native-webview as it has been deprecated from react-native and will be removed in future release.

See https://facebook.github.io/react-native/docs/webview for more info.

awesome! Thanks for the PR. I'll check it out later today and merge it.

A couple of things:

• I think we will also need to add react-native link react-native-webview to the install instructions.
• It looks like the import in iosWebView.js should be import { WebView } from "react-native-webview";

Also, it looks like there is a PR in react-native-webview to add this functionality. If it works in a similar way, I will likely deprecate this library in favor of that:
react-native-webview/react-native-webview#325

Some more changes seems to be required for android, I made another PR #28
