Mixen合并 JavaScript 类

Mixen 可以让你随时对类进行合并，使用它可以构建更小、更易于理解和更方便测试的组件，以及更方便的和他人分享代码。

class MyModel extends Mixen(Throttle, APIBinding, Validate, Backbone.Model)
  # Inheritance Chain:
  #
  # MyModel -> Throttle -> APIBinding -> Validate -> Backbone.Model

class MyOtherModel extends Mixen(APIBinding, Backbone.Model)
  # Inheritance Chain:
  #
  # MyOtherModel -> APIBinding -> Backbone.Model
