Get the first event in a set of event emitters and event pairs,
then clean up after itself.
## Install
```sh
$ npm install ee-first
```
## API
```js
var first = require('ee-first')
```
### first(arr, listener)
Invoke `listener` on the first event from the list specified in `arr`. `arr` is
an array of arrays, with each array in the format `[ee, ...event]`. `listener`
will be called only once, the first time any of the given events are emitted. If
`error` is one of the listened events, then if that fires first, the `listener`
will be given the `err` argument.
The `listener` is invoked as `listener(err, ee, event, args)`, where `err` is the
first argument emitted from an `error` event, if applicable; `ee` is the event
emitter that fired; `event` is the string event name that fired; and `args` is an
array of the arguments that were emitted on the event.
```js
var ee1 = new EventEmitter()
var ee2 = new EventEmitter()
first([
[ee1, 'close', 'end', 'error'],
[ee2, 'error']
], function (err, ee, event, args) {
// listener invoked
})
```
#### .cancel()
The group of listeners can be cancelled before being invoked and have all the event
listeners removed from the underlying event emitters.
```js
var thunk = first([
[ee1, 'close', 'end', 'error'],
[ee2, 'error']
], function (err, ee, event, args) {
// listener invoked
})
// cancel and clean up
thunk.cancel()
```
