## How to use

```js
const bunyan = require('bunyan')
const cueball = require('cueball')
const restifyClients = require('restify-clients')
const Resolver = require('cueball-resolver')

const agent = new cueball.HttpAgent({
  log: bunyan.createLogger({
    name: 'agent-test',
    level: process.env.LOG_LEVEL || 'error'
  }),
  spares: 2,
  maximum: 4,
  recovery: {
    default: {
      timeout: 50,
      retries: 2,
      delay: 5,
      maxDelay: 50
    }
  }
})

const client = restifyClients.createStringClient({
  url: 'http://test.host.com',
  agent
})

const resolver = new Resolver({
  backends: [
    {
      address: '127.0.0.1',
      port: 1234
    }
  ]
})

resolver.start()

agent.createPool('test.host.com', {
  resolver
})

client.get('/test', (err, req, res, data) => {}
```
