#hof-behaviour-hooks

HOF Behaviour enabling lifecycle hooks for extending functionality in main form pipeline.

###With mixwith.js

const mix = require('mixwith').mix;
const Hooks = require('hof-behaviour-hooks');
const BaseController = require('hof-form-controller');

class MyController extends mix(BaseController).with(Hooks) {
...
}
`
MyController now extends hof-form-controller and has hof-behaviour-hooks functionality mixed in.
