Document how to promisify with bluebird

[fiducioso-dan]

This library looks really nice and I was going to use it for a small project, but I can't figure out how to promisify it with bluebird. If you put a little code snippet in the readme showing how it would make the library more usable.

Here is the wrapper I use that provides a promisified library.

'use strict';
var P = require('bluebird')
var cradle = require('cradle')

var CouchSchema = require('./CouchSchema')

var config = require('../config')

//make some promises
P.promisifyAll(cradle)

//setup our client
var client = new (cradle.Connection)(
  config.couchdb.host,
  config.couchdb.port,
  config.couchdb.options
)

//make some promises
P.promisifyAll(client)


/**
 * Setup the DB access
 * @type {object}
 */
client.db = P.promisifyAll(client.database(config.couchdb.database))


/**
 * Add schema to helper
 * @type {CouchShema}
 */
client.schema = new CouchSchema(config.couchdb.prefix)


/**
 * Export client
 * @return {object} client
 */
module.exports = client

Please provide this kind of wrapper as part of Cradle. "It's the current year!"

honestly callbacks should be removed completely (except for events), bad for readability, bad for error handling (especially when you try to promisify it, because bluebird is a mess when it comes to errors)
