【银行管理系统】先实现一个普通窗口为普通客户服务，快速Vip类比

银行业务调度系统

模拟实现银行业务调度系统逻辑，具体需求如下：

Ø 银行内有6个业务窗口，1 - 4号窗口为普通窗口，5号窗口为快速窗口，6号窗口为VIP窗口。

Ø 有三种对应类型的客户：VIP客户，普通客户，快速客户（办理如交水电费、电话费之类业务的客户）。

Ø 异步随机生成各种类型的客户，生成各类型用户的概率比例为：

        VIP客户 ：普通客户 ：快速客户  =  1 ：6 ：3。

Ø 客户办理业务所需时间有最大值和最小值，在该范围内随机设定每个VIP客户以及普通客户办理业务所需的时间，快速客户办理业务所需时间为最小值（提示：办理业务的过程可通过线程Sleep的方式模拟）。

Ø 各类型客户在其对应窗口按顺序依次办理业务。 

Ø 当VIP（6号）窗口和快速业务（5号）窗口没有客户等待办理业务的时候，这两个窗口可以处理普通客户的业务，而一旦有对应的客户等待办理业务的时候，则优先处理对应客户的业务。 

Ø 随机生成客户时间间隔以及业务办理时间最大值和最小值自定，可以设置。

Ø 不要求实现GUI，只考虑系统逻辑实现，可通过Log方式展现程序运行结果。

可以通过修改各种窗口的数量来观察现象
