Detailed Description

Hold a pointer to the current event store.

Athena has a notion of a ‘current’ event store. This is used, for example, when ElementLinks are initialized without explicitly specifying the store.

Be aware that the current event store is thread-specific and thus fetching it is relatively expensive. It would be better to move calls to store() outside of loops.
