在Ember 2.0组件工厂中，必须将`isComponentFactory`属性设置为true

Question

使用扩展Ember.Checkbox的组件时，我收到此弃用警告：

In Ember 2.0 component factories must have an `isComponentFactory` property set to true. You registered (subclass of Ember.Checkbox) as a component factory. Either add the `isComponentFactory` property to this factory or extend from Ember.Component.

我很感激对这背后逻辑的一个很好的解释。
