EntityChangedInterface

Defines an interface for entity change timestamp tracking.

This data may be useful for more precise cache invalidation (especially on the client side) and concurrent editing locking.

The entity system automatically adds in the 'EntityChanged' constraint for entity types implementing this interface in order to disallow concurrent editing.
