description:
  This library provides a timer wheel data structure for registering one-shot or recurring @IO@ actions to fire after a
  given amount of time.
  .
  It is similar to @TimerManager@ from @GHC.Event@, but supports recurring actions, and can scale to handle many more
  registered actions.
