设计一个处理复数运算的类，该类中至少有两个成员方法： 复数加法和复数减法运算。 在上述类中添加两个静态方法：求一个复数的模和求一个复 数的复角。 设计一个子类，该子类继承了上述的类，并且至少拥有自己 的两个方法：复数乘法和复数除法。 再设计一个类，包含main方法，对上面的类进行应用与测试。 该作业要求编程并调试通过。对你设计的类要有详细的文字 说明（类所封装的内容，属性、方法的功能与含义等）(The design of a complex operation processing class, at least two members of the methods in this class. Complex addition and subtraction.)

TODO(code review): Curious question.. Why are a lot of these methods not declared as static, since they do not seem to require any local object state? Assumedly this cannot be changed without interfering with the API..
