```
    Implements a 'Add Set' CRDT, also called a 'G-Set'. You can't remove elements of a G-Set.
    It is described in the paper A comprehensive study of Convergent and Commutative Replicated Data Types.
    A G-Set doesn't accumulate any garbage apart from the elements themselves.
    This class is immutable, i.e. "modifying" methods return a new instance.

```
public scala.Option<GSet<A>> delta()

    Description copied from interface: DeltaReplicatedData
    
    The accumulated delta of mutator operations since previous DeltaReplicatedData.resetDelta(). When the Replicator invokes the modify function of the Update message and the user code is invoking one or more mutator operations the data is collecting the delta of the operations and makes it available for the Replicator with the DeltaReplicatedData.delta() accessor. The modify function shall still return the full state in the same way as ReplicatedData without support for deltas.

```
public GSet<A> zero()

    Description copied from interface: ReplicatedDelta
    
    The empty full state. This is used when a delta is received and no existing full state exists on the receiving side. Then the delta is merged into the zero to create the initial full state.
    
    Specified by:
    
    zero in interface ReplicatedDelta
  - resetDelta
```
public GSet<A> resetDelta()
```
    Description copied from interface: DeltaReplicatedData
    
    Reset collection of deltas from mutator operations. When the Replicator invokes the modify function of the Update message the delta is always "reset" and when the user code is invoking one or more mutator operations the data is collecting the delta of the operations and makes it available for the Replicator with the DeltaReplicatedData.delta() accessor. When the Replicator has grabbed the delta it will invoke this method to get a clean data instance without the delta.
