Base class for something that can happen during a simulation (such as an observation).
Derived events must have a compute_tags_for_observation_box that is a tmpl::list of simple or compute tags. Simple tags are assumed to already be in the DataBox. Evolved variables, for example, would be listed as simple tags. The compute tags are used to compute additional quantities that may be observed. For example, in the scalar wave system the 1- and 2-index constraints would be added as compute tags, as well as anything they depend on that's not already in the DataBox.

Whether the event uses anything depending on the evolved_variables. If this returns false, anything depending on the evolved variables may have an incorrect value when the event is run.
