GrowMap

A GMap (Grow-only Map) is a Delta CRDT that models a map from an arbitrary key type to nested Delta CRDTs. In contrast to ORMapInterface, key/value pairs cannot be removed from this map. However, due to the smaller internal representation, mutate operations on large maps are a lot faster than on ObserveRemoveMap.

The nested CRDTs can be queried/mutated by calling the queryKey/mutateKey methods with a DeltaQuery/DeltaMutator generated by a CRDT Interface method of the nested CRDT. For example, to enable a nested EWFlag, one would pass EWFlagInterface.enable() as the DeltaMutator to mutateKey.
