Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public static interface FunctionalInterfaces.Intx4ToDom
```
Represents a function that associates an integer domain (possibly, null) with four given integers. This is a functional interface whose functional method is apply(int,int,int,int) . This may be useful when building 4-dimensional arrays of integer variables as for example in:
```
 Var[][][][] = array("x", size(10, 5, 3, 3), (i,j,k,l) -> i+j == k+l ? dom(range(10)) : dom(0,1));
 
```
On our example, some variables have a domain containing 10 values whereas others have a domain containing two values only.
