1. Default usage:

   use Zippovich2\EventDispatcher\EventDispatcher;
   
   $dispatcher = new EventDispatcher();
   
   // Add subscriber to events
   $dispatcher->subscribe('event1', 'Subscriber::callback');
   $dispatcher->subscribe('event2', 'Subscriber::callback2');
   
   // Getting event subscribers
   $event1Subscribers = $dispatcher->getSubscribers('event1');
   
   // Or get subscribers from all events
   $allSubscribers = $dispatcher->getSubscribers();
   
   // Dispatch event
   $dispatcher->dispatch('eventName');

2. Using TraceableEventDispatcher:

   use Zippovich2\EventDispatcher\TraceableEventDispatcher;
   
   $dispatcher = new TraceableEventDispatcher();
   
   // Add subscriber to events
   $dispatcher->subscribe('event1', 'Subscriber::callback');
   $dispatcher->subscribe('event2', 'Subscriber::callback2');
   
   // Dispatch event return callstack tree
   $callstackTree = $dispatcher->dispatch('eventName');
      
   // Getting raw callstack
   $callStack = $dispatcher->getCallStack();
