ObserveRemoveMap

An ObserveRemoveMap (Observed-Remove Map) is a Delta CRDT that models a map from an arbitrary key type to nested causal Delta CRDTs. In contrast to GrowMap, ObserveRemoveMap allows the removal of key/value pairs from the map.

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.
