高性能优惠叠加计算框架

q-calculator's Issues

是否可以考虑再增加一部分案例或者提供更详细的文档？

您好：
目前看完介绍跑完demo有一些疑惑的点：

1. 关于互斥组，目前是支持2个，会转换成共享组，

类似如果用户包含的资产里面有A,B,C,D：（A,B）互斥 ，（C,D）互斥，(B,D)互斥，(A,C)(B,C)(A,D) 共享，不太理解按现有结构要如何配置才能支持

2. 关于自定义的规则部分，目前demo里面有满减和折扣的示例，但是，不是很清晰

类似：如果券作用是在单商品上的，只能被用一次（多个数量只能用一个），代码里面有个records描述可以记录商品的优惠，自定义逻辑。
方便的话可以给个示例，还有有些券被商品使用了，需要标记被使用，不能参与计算了，这种。

final DiscountConfig discountConfig = new DiscountConfig();
        discountConfig.setCalculateGroup(10);
        discountConfig.setGoodsType(1);
        discountConfig.setItemIds(ImmutableList.of(1001L));
        discountConfig.setItemIdType(0);

{
    "6667": [
        {
            "beforeCalcPrice": 10000,
            "afterCalcPrice": 8000,
            "stageType": "manjian",
            "index": 0,
            "extra": null
        },
        {
            "beforeCalcPrice": 8000,
            "afterCalcPrice": 6667,
            "stageType": "zhekou",
            "index": 1,
            "extra": null
        }
    ]
}

如果可能的话，可以把文档更详细一些，或者一个相对复杂的使用示例，会更方便理解。

最后，之前没有接触过电商项目，所以比较小白
在找到这个仓库之前：
看了 严选促销中心价格计算体系的建设之路, vivo商城计价中心 看着场景都很符合，但是自己一个人实现就头大了，都很困难。

全网或许只有你们一个开源这种算法的，非常感谢。

Suggestion to add a license file to the repository

Hello! I came across your code and I was wondering if you have considered adding a license file to your repository. A license file is a way of letting others know how they can use or modify your code legally. Without a license file, your code is technically not open source and no one can use it without your permission. This might limit the potential impact and reach of your project. GitHub recommends that you include a license in your repository to let others know how can your code be used and built upon (Source: Licensing a repository). If you are interested in making your project open source, you can check out Choosing a license to learn more about the different types of licenses and their benefits.

To add a license file to your repository, you can follow the steps in this guide: Adding a license to a repository. You can also read this article for more information on open source licensing: Open Source Licensing Guide.
