#GSimpleEvents This provides a utility class called Events.

Would be nice if sometimes you could add custom events to an object in your code. This class provides that basic functionality.

#Usage

To use this, create a new events object, passing in an array of named events

let events = new Events(['onFileUpload', 'onUserIdle']);

or, if you're in a class:

this.events = new Events(['onClosed', 'onMinimized', 'onResized']);

after it's constructed, listeners can be added:

let id = someObject.events.onClosed.addListener((optionalParameters) => { // do a thing })

This will return an ID number which you can use to remove the listener later, or just pass the function in if it's not anonymous.

someObject.events.onClosed.removeListener(id).

The even can be fired like so:

events.onClosed.fire([optional, parameters, array])

The parameters passed into fire will be applied to the callback, as input parameters (not as an array)
