/**
* The EventSystem has the following requirements:
*
* * Mainly similar to guava EventBus
* * Multiple EventBuses possible.
* * Each EventBus offers methods to register and unregister handlers as well as post to post an event
* * Handlers are registered as WeakReference
* * You can specify the target for an event by annotation:
* ** CDI: will forward the event to CDI +
* ** JFX: will forward the event to the current JavaFX Stage
* ** None: default case
* * You can also specify the threads for an event by annotation:
* ** Same: default case for synchronous invocation
* ** JFX: will execute the event in the JFX thread
* ** Async: will execute the event in the default work stealing executor.
* * In the thread annotation you can specify if the handlers should wait for the event or not.
* * An event can be consumed, so it will not be propagated to further handlers.
* The consumption occurs if the handler method returns a boolean which is set to true.
* * Sorting of handlers via @Priority marker
