Small utility function to automatically retry bluebird Promises.
## Install
```bash
npm install --save retry-promise
```
## Usage
`retry(opts, promise)`
`opts.max` max number of retries (default: `10`)
`opts.backoff` time in ms between retries (default: `1000`)
Time between retries is actually attempt_number * backoff.
Every retry waits longer.
## Example
```javascript
var retry = require('retry-promise');
retry({ max: 3, backoff: 1000 }, function (attempt) {
console.log('Attempt', attempt, 'at creating user');
return User
.forge({ email: 'some@email.com' })
.createOrLoad();
})
.then(function (user) {
req.user = user;
next();
})
.catch(next);
```
