Proposal for a wrapper handler in the express way

[pjnovas]

Hey there, this lib is awesome!, it's exactly what I was looking for.

So I wanted to push a little more forward the handler func to express like and I made a wrapper on my project like this:

// file: chain.js
import Series from 'hapi-next';

export default function() {
  let funcs = Array.prototype.slice.call(arguments);
  return function (request, reply){
    (new Series(funcs)).execute(request, reply);
  }
}

And at my controller I have:

// file: eventController.js
import chain from './chain';

const fetchEvent = async (request, reply) => { /*...*/ reply.next() /*...*/ }
const isEventOwner = async (request, reply) => { /*...*/ reply.next() /*...*/ }

exports.remove = {
  auth: 'simple',
  // Below is where I use it
  handler: chain(fetchEvent, isEventOwner, async (request, reply) => {
    await request.event.remove();
    return reply().code(204);
  })
};

The main idea is to use that function chain as the hapi handler in the exact same way as express.
I think it would be awesome to have a function wrapper in that way at the core of this library, what do you think?

Thanks again for this piece of work 👍
