Add a inherits method to complement util.inherits

[oliverzy]

Hi,

I'm looking for a traits implementation in JS and found this one is pretty interesting.
As you know, Node.js has a util.inherits method to simplify inheritance.

In terms of traits, it seems we need a similar util function that can combine util.inherits and traits together, that's what I have written.
I use lodash extend method for simplicity.

function inherits(constructor, parentConstructor, trait, properties) {
  util.inherits(constructor, parentConstructor);
  if (properties !== undefined)
    _.extend(constructor.prototype, properties);
  if (trait !== undefined)
    constructor.prototype = trait.create(constructor.prototype);
}

Hey @oliverzy to be honest I'm no longer interested in this module, if you are I'm happy to give you ownership and you can do whatever you like with it :)
