A [PSR-14](https://www.php-fig.org/psr/psr-14/) implementation which uses a [Resolver](src/DI/) to inject dependencies from a container when resolving EventListeners.

A [SortingAlgorithm](src/Sort/SortingAlgorithm.php) prioritizes event->listener [Subscriptions](src/Subscription/Subscription.php) at execution time. Priortization occurs in [ListenerProvider](https://github.com/NathanBurkett/event-dispatcher/blob/863dfd208167435f6be6ec27e7af51958e8a1976/src/Listener/Provider/ListenerProvider.php#L119) and observes priority from highest to lowest.

This means a ListenerProvider can already have multiple Subscriptions but could [add another](https://github.com/NathanBurkett/event-dispatcher/blob/863dfd208167435f6be6ec27e7af51958e8a1976/src/Listener/Provider/ListenerProvider.php#L54) at run time whose priority facilitates the EventListener being handled first:
