> Data Exchange component that uses other peers to exchange requests/responses

## Use-Case

The use case for this exchange component is to allow exchanges between two peers that are not directly connected but share one or more rendezvous peers.

## Example

```js
'use strict'

const Exchange = require('libp2p-exchange-direct')

const exchangeA = new Exchange(swarmA)
const exchangeB = new Exchange(swarmB)
const exchangeM = new Exchange(swarmM, {enableServer: true})

exchangeA.start(() => {})
exchangeB.start(() => {})
exchangeM.start(() => {})

exchangeB.listen('example', (data, cb) => {
  return cb(null, data.reverse())
})

swarmA.dial(swarmM.peerInfo, err => {
  if (err) throw err

  swarmB.dial(swarmM.peerInfo, err => {
    if (err) throw err

    exchangeA.request(swarmB.peerInfo.id, 'example', Buffer.from('Hello World!'), console.log)
  })
})
```
