All Known Implementing Classes:

Binary, InflatableSet
```
public interface Nullable<T>
```
An interface that any class can implement to mark itself as "nullable", which allows it to be used in a more optimal way with collections that support "nullable" keys and/or values.
While technically not a marker interface, this interface can typically be used as such as it provides a reasonable default implementation of the get method that simply returns the instance itself.
The rest of the methods in this interface are static factory methods that allow creation of a Nullable values from various primitive, wrapper and reference types, as well as a static get(Nullable) method that allows you to "unwrap" any Nullable and return either the value itself or a null, if the specified Nullable is empty.
