Mixto: A simple mixin superclass

To create a mixin, subclass mixto:

Mixin = require 'mixto'

class MyMixin extends Mixin
  @classMethod: -> console.log("foo")
  instanceMethod: -> console.log("bar")

Then mix into classes with .includeInto:

class MyClass
  MyMixin.includeInto(this)

MyClass.classMethod()
(new MyClass).instanceMethod()

Or extend individual objects with .extend:

myObject = {a: 1, b: 2}
MyMixin.extend(myObject)
myObject.instanceMethod()

Or build standalone instances of your 'mixin':

standalone = new MyMixin
standalone.instanceMethod()
