/**
* Marks a method as an event subscriber.
*
* The type of event will be indicated by the method's first (and only) parameter. If this
* annotation is applied to methods with zero parameters, or more than one parameter, the object
* containing the method will not be able to register for event delivery from the {@link EventBus}.
*
*
Unless also annotated with @{@link AllowConcurrentEvents}, event subscriber methods will be
* invoked serially by each event bus that they are registered with.
