Mixto: A simple mixin superclass 

To create a mixin, subclass mixto:

``coffee
Mixin = require 'mixto'

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

Then mix into classes with .includeInto:

`coffee
class MyClass
MyMixin.includeInto(this)

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

Or extend individual objects with .extend:

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

Or build standalone instances of your 'mixin':

`
standalone = new MyMixin
standalone.instanceMethod()
``
