/**
* The `mixin` utility assigns the properties of a set of 'mixin' objects to
* the prototype of a parent object.
*
* @example
* class MyClass extends mixin(ExistingClass, evented, etc) {}
*
* @param {Class} Parent The class to extend the new class from.
* @param {...Object} mixins The objects to mix in.
* @return {Class} A new class that extends Parent and contains the mixins.
