## Intent
Event Queue is a good pattern if You have a limited accessibility resource (for example:
Audio or Database), but You need to handle all the requests that want to use that.
It puts all the requests in a queue and process them asynchronously.
Gives the resource for the event when it is the next in the queue and in same time
removes it from the queue.

## Applicability
Use the Event Queue pattern when
* You have a limited accessibility resource and the asynchronous process is acceptable to reach that
