set withing a context. This is especially useful for unmounting listeners in
React's componentWillUnmount lifecycle event.

Installation

``bash
$ npm i --save ensemble
`

`js
var Emitter = require('events').EventEmitter;
var ensemble = require('ensemble');

/**
* Wrap an event emitter.
*/

var emitter = ensemble(new Emitter);

/**
* Attach listeners to the emitter.
*/

emitter.on('foo', function() {});

/**
* Remove all listeners registered
* in the wrapper from the emitter.
*/

emitter.removeListeners()
`
