原创设计模式 - 抽象工厂模式（Abstract Factory） C++实现

抽象工厂模式（Abstract Factory）意图：提供一个创建一系列相关或相互依赖对象的接口。之前的工厂方法模式，每增加一个产品，就需要增加一个具体产品类和一个对于工厂类。对于一些情况，比如设计一个UI库，有按钮、滚动条等组件，为了让程序更加个性化，需要实现程序可以换皮肤的功能，比如蓝色主题、红色主题等，而且要便于拓展新的主题。如果用工厂方法模式来实现的话，对每个组件都要一个相

原创设计模式 - 简单工厂模式/静态工厂模式（Static Factory Method） C++实现

简单工厂模式简单工厂模式又叫静态工厂方法，不属于23种GOF模式之一。适用场景：在程序的各个地方都需要new一些常用的对象，并且对new的对象要进行一些初始化，new操作散落在程序的各个地方，不便于管理和维护，因此引入简单工厂模式来统一管理常见对象的创建。客户调用工厂的方法，得到需要的产品，无需自己创建产品。工厂根据客户传入的参数或者配置文件来决定创建什么类型的产品。
