Indexable

```
public interface Indexable
```
An interface implemented to let users access data classes via an Indexer. The class implementing this interface can choose the type (byte, short, etc.) of the indexer, and whether it is array-based or direct. The Indexer.release() method should also be overridden to copy back any data written in the case of non-direct indexers.
