实现中等难度通讯录(字典，属性，…
需求:
1、定义联系⼈类 AddressContact。
实例变量:姓名(拼⾳,⾸字⺟大写)、性别、电话号码、住址、分组名称、年龄。
方法:⾃定义初始化方法(姓名、电话号码)、显示联系⼈信息。
2、在main.m中定义字典,分组管理所有联系人。分组名为26个⼤写的英⽂字⺟。
3、可以添加联系人对象,如果姓名或电话号码为空,添加失败。添加联系⼈到匹配的分组。
4、获取某个分组名称下所有联系⼈,并且按照姓名升序排列。
5、从通讯录中根据电话号码搜索联系人。
6、获取所有女性的联系人,并且按照年龄的降序排列。
7、根据姓名删除某个联系人。
8、删除某个分组的全部联系人。
