Manage collections of listener functions/callbacks
npm install listenersRepresents a collection of registered listener functions, with methods for adding, removing and calling all functions.
Get it:
``shell`
npm install --save listeners
Require it:
`javascript`
var Listeners = require('listeners');
#### 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.
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.
