Offers a way to mix-in generators

[SBoudrias]

ATM the only built-in way to reuse functionalities with Yeoman is inheritance:

var BaseGen = generator.Base.extend();
var myGenerator = BaseGen.extend();

That's fine, but it's hard to share multiple decoupled functionalities as prototypes only support single inheritance.

We could offer a way to easily mix-in functionalities in Yeoman. That's the API I have in mind:

var mixin = require('yeoman-mixin');

var myMixin = mixin({
  prompting: function () {},
  _someMethod: function () {}
});

var Generator = generator.Base.extend({
  prompting: function () {}
});
myMixin.mix(Generator);

Which would basically results in:

Generator.prototype.prompting.prompting1 = function () {};
Generator.prototype.prompting.prompting2 = function () {};
Generator.prototype._someMethod = function () {};

This can be done pretty easily. I wonder if we should make it more complex by separating scope between mixins and original prototype or something like that... Maybe something to consider later on?

I like that idea! 👍
