Annotation<T> class
Annotations are tagged values that are used to add metadata to transactions in an extensible way.
They should be used to model things that affect the entire transaction (such as its Transaction.time or information about its Transaction.userEvent). For effects that happen alongside the other changes made by the transaction, StateEffect is more appropriate.
