### createEventHub
Creates a pubsub event hub with `emit`, `on`, and `off` methods.
Creates a pub/sub ([publish–subscribe](https://en.wikipedia.org/wiki/Publish%E2%80%93subscribe_pattern)) event hub with `emit`, `on`, and `off` methods.
For `emit`, resolve the array of handlers based on the `event` argument and then run
each one with `Array.forEach()` by passing in the data as an argument.
