Optional.OrElse (Jong-Soft Java Language Extensions 1.1.2 API)

Enclosing interface:

Optional<T>
```
public static interface Optional.OrElse
```
The OrElse interface is an extension to the Optional interface. This interface can be used to cascade behaviour when an entity is or is not present in the wrapper.
For example if the Optional has no entity contained within then the OrElse can be used to throw an exception or run alternative logic.

Example:
```
 API.Option(null)
      .ifPresent(System.out::println)
      .elseThrow(() -> new NullPointerException("No value present"))
 
```
