Superclass that provides methods to access the underlying native component.
This can be useful when you want to focus a view or measure its dimensions.

Methods implemented by this class are available on most default components
provided by React Native. However, they are *not* available on composite
components that are not directly backed by a native view. For more
information, see [Direct Manipulation](docs/direct-manipulation.html).
