Minor output typo

In the section describing the usage of `"super"`, example output says `// White Rabbit stands still. White rabbit hides!`

The `name` member in this example is set to `White Rabbit`, so the second sentence above should say `White Rabbit hides!` (capital R)

 Now `Rabbit` has the `stop` method that calls the parent `super.stop()` in the process.
