DottedDecompose

Decompose a state into smaller parts. Note that the goal here is small individual storage size at reasonable computational cost. Minimalism of returned results is not guaranteed. It is also not guaranteed that the result does not overlap.

computes delta without state

Lattice order is derived from merge, but should be overridden for efficiency

By assumption: associative, commutative, idempotent.

For use with Delta CRDTs, this function should be optimized for the case that left >> right, i.e., that left is the current state and right the delta
