Rename ToastAndroid to ToastExample

Summary:
The `ToastAndroid` module already exists in react native. In its current form, the tutorial will cause an error, as then there would be two `ToastAndroid`s. This PR addresses that by naming the new module `ToastExample`.

Tested this by running the doc website with my changes, here's a clip

The production site with the old doc has 14 `ToastAndroid`s, with one referring to the real module doc

This PR now as 13 `ToastExample` references, one less because the `ToastAndroid` module is still on the left-side doc, as it should be.

This guide will use the [Toast](http://developer.android.com/reference/android/widget/Toast.html) example. Let's say we would like to be able to create a toast message from JavaScript.
We start by creating a native module. A native module is a Java class that usually extends the `ReactContextBaseJavaModule` class and implements the functionality required by the JavaScript. Our goal here is to be able to write `ToastAndroid.show('Awesome', ToastAndroid.SHORT);` from JavaScript to display a short toast on the screen.

`ReactContextBaseJavaModule` requires that a method called `getName` is implemented. The purpose of this method is to return the string name of the `NativeModule` which represents this class in JavaScript. So here we will call this `ToastAndroid` so that we can access it through `React.NativeModules.ToastAndroid` in JavaScript.

Now, from your other JavaScript file you can call the method like this:
```js
import ToastAndroid from './ToastAndroid';
import ToastExample from './ToastExample';
ToastAndroid.show('Awesome', ToastAndroid.SHORT);
ToastExample.show('Awesome', ToastExample.SHORT);
```
