API

var listeners = new Listeners([onError])

listeners.add(fn, [ctx])

listeners.remove(fn, [ctx])

listeners.clear()

listeners.fire(args...)

listeners.fireArray(args)

Listeners.onError(errorHandler)

Set the default error handler for new instances.

Error Handling

Should a listener function throw an error, the default behaviour is to log it and continue firing any remaining listeners. This behaviour can be overridden by passing an error handling to the Listeners constructor, or by setting a default error handler. An error handler can return false to indicate that no further listener functions should be triggered for this event, or alternatively you can rethrow the exception and it will be propagated to as usual.
