EspressoOptional

This is currently not recommended for use and will be deprecated in the future. New APIS should use Nullable annotation instead.

Parameters
`<T>`	the type of instance that can be contained. `Optional` is naturally covariant on this type, so it is safe to cast an `Optional<T>` to `Optional<S>` for any supertype `S` of `T`.
